To follow on from Darkward's post, and whether or not the OP sees this response, I regret that anyone felt the need to post it in the first place. I always hope that PSDH generally has a good reputation and I want to know if someone is seriously bad-mouthing etc. other players. If someone is getting out of hand in public chat channels I will (if I see it) ask them to rein it in a bit, but I'm not omniscient - if my attention is elsewhere or if there's stuff being said in /say chat that's out of range I won't know about it
I've said it before and will say it again: I will not tolerate bigotry, racist, homophobic or misogynistic comments from guild members. I suspect that a great deal of the chat which could be seen as 'verbal attacks' are misunderstood map-chats between people that know each other well-enough to not take offense. However if other people
are misunderstanding / taking offense at what is being said then we all need to take the time to think about what we say in public channels and how we say it. It is all too easy for someone to take something out of context or misinterpret what was intended as banter as something more offensive.
That said, we all get frustrated from time to time especially if there are trolls on the map... if someone is looking to get into a verbal sparring match with us there are those in the guild who will oblige... personally I try to make a joke out of it and if they continue to be obnoxious I just block them when it becomes apparent that they're going to be intransigent...
To reiterate Dark's point about 'claiming' a map; we do not do this to exclude anyone, or to be arrogant or blow our own trumpets... rather to announce that we are there to avoid clashing with another guild organisation and indeed to invite non members to join us. PSDH is all about facilitating the large events for people who might not otherwise get the opportunity to enjoy them: if we do get annoyed with people in map chat it is generally those who seem to go out of their way to prevent us from succeeding in getting as many people participating as possible. Because those non-members cannot see guild chat and we generally do try to provide some semblance of organisation the easiest way to establish interested numbers and communicate to them directly is via Teamspeak, so we invite them to join us.
Asking people if they wouldn't mind switching maps when a map is just that: a request. It is not an order - and certainly not something we can enforce. Personally I always try to ask as politely as possible. it's done simply as a means by which we hope to increase the number of people participating in the event. If you're (for example) farming candy-corn at Barrier Camp, or doing Sparkfly daily events, you can do those on any map instance and get the same experience: simply logging to the character select screen and back in again will probably log you into a different map instance and enable someone who was trying to join the event to be able to get into the map.
TT Wurm and, to a lesser extent, Tequatl require a certain minimum number for success and because of the way the events are timed we often end up with a map instance where we have people stuck outside wanting to join but unable to do so because the map has capped (about 150 people). This is especially annoying where someone who turned up early for an event has DC'd / lagged out and is unable to rejoin the map because it is full of people who have no interest in doing 'the main event'. Being stuck outside the map when all your guildies are doing an event is really frustrating!
Similarly, I'm sure we could do events without Teamspeak; at least Tequatl does not require any great amount of coordination these days. The reasons we ask people to use Teamspeak are as follows:
1) It is easier to communicate to large numbers of people through voice chat, whilst doing the events... if you're typing then you're not moving or attacking. Talking is quicker and generally less likely to be misunderstood.
2) As anyone who has commanded events knows, typing the same (or similar) things several times over will lead to in game chat messages getting suppressed, which you really don't want in the middle of an event. Suddenly you can't communicate with people at all. Sure, you can get some people to join squad chat which doesn't get suppressed, but a lot of people don't read even /say chat. Talking is simply more effective and efficient than typing.
3) If you know an event well enough that you can do it and follow the commander with your eyes closed then good for you, but you are in the minority. Far too many players still do not understand how the TT Wurm event really works, and will run around doing their own thing ignoring the commander because hey, it's GW2 - you can autoattack to win right? Sorry but TT Wurm don't work that way. If you find it's easy now that's because a lot of us spent a good few months failing it over and over, learning the hard way how the event works and most importantly sharing that information with others... mostly via Teamspeak!
If you think that an uncoordinated map can beat the TT Wurm then I invite you to try pugging the event some time. Believe me as commanders we can tell when who is on Teamspeak and who isn't. Admittedly, TT Wurm is certainly easier now than it used to be - certainly there are people who have succeeded in the event many times and whilst it isn't necessary for every last person to be on TS, especially if you know the event, it is necessary to have a 'critical mass' of people to provide the 'core zerg' on which the others can stack.
Anyone who thinks Amber or Cobalt can be done as an uncoordinated mass does not understand the finer points of the event. Even if you know
what to do, it is the commander's job to coordinate
when everyone should do it (preferably at the same time). If most of the zerg are not on TS then it gets very messy when, for example you think you should be running kegs but the commander has decided the beach needs cleaning of wurms or there was an eggblocking failure which was announced on TS, but hey, you didn't hear that because you're too uber to join us.
4) Teamspeak allows us to share /join (taxi) info via a channel which is specific to the event. This is useful when we are establishing a map to get our members in place simply because you can copy text from TS to the game chat...text chat copy is something that is sadly lacking from the in-game chat window. It prevents accidentally typing someone's name incorrectly and /joining on the wrong person and, if that person's name contains special characters that don't appear on your language keyboard it makes it possible to /join on them at all.
Furthermore, PSDH is a world boss guild comprising members from many guilds - some of whom require 100% repping. We do not require people to rep PSDH during events but we do need to be able to communicate with them, both to inform them of upcoming events and to command during events. Teamspeak provides us with that facility without people necessarily having to rep PSDH all night.
Finally we often have a lot of fun in TS... if you're not joining then you're missing out

Just to remind everyone (again) - the two core tenets of PSDH membership are - Play Nice (and be on TS for events!)
