So tell me how, an addon which will enable things I can already do, will make me go back to a server I don't want to be on? Oh "because you can have your own channel identity?" Please...
For a lot of people--maybe not yourself, but many--they started on AP and had to leave to another server because A) there was only one chat and it became polluted with newcomers with bad attitudes or simply took on a tenor that they no longer felt comfortable with, and B) they were powerless to do anything about it other than to shut off chat completely, thus cutting themselves off from the people that they -did- want to communicate with, or take themselves and those people and start all over again on another server.
The ability to have multiple channels on the F2P addon is a very new development, and (as I said) could be implemented with much more robustness with new code. But the habit of splitting off into different servers, and self-identifying with a server rather than a group of people, far predates even the most basic ability to split F2P chat. In short, I expect that MANY of us, myself included, would have taken the option of setting up guild-like channels rather than abandoning our hard work on our characters to reroll, if that option had been open to us at that time.
You state that you don't want to be on Aerie Peak, but you don't state your reasons why. I don't want to speculate about your own personal reasons unless you choose to share them, but for anyone else in the same position, where they don't want to be on Aerie Peak (or any other megaserver for that matter) because of all the chaos that a megaserver represents, then they shouldn't overlook how having these options removes those complaints. Saying that one doesn't want to be on Aerie Peak the way it is now, is not relevant. Heck, I don't want to be on Aerie Peak the way it is now, and I miss the original Kincaide terribly. But to say that one doesn't want to be on Aerie Peak in a better future, simply because of what Aerie Peak is now, seems to me to be short-sighted. If, as I said, the problems people have with Aerie Peak are based on the unavoidable elements that are there now, and the new paradigm allows you to avoid those elements, then what would the problem be at that point?
Also, if you have no intention of rerolling that's fine, but please don't speak for anyone else in that regard. I have three BIS characters on Vashj and three near-BIS characters on Misha, and only two BIS characters on AP, so I would have as much to lose in this new idea as anyone. But the idea of having huge world PVP events, constant arenas running, wargames whenever we wanted them, and dozens more like-minded people all on one server from whom we could pick the people with whom we identified the most, would for me make any discomfort in moving back well worth it. It may not be for you, and that's fine. But each person's going to have their own opinion on that, so let them speak it.
