My guild and I transferred from Blacktide to Gandara when the opportunity came up. Many of us were regular wvw’ers in BT but the massive prevalence of Polish guilds and players in that server, and the consequent numbers of Polish commanders led to most of the English speaking guilds leaving or disbanding altogether. It is primarily their insistence on speaking only polish on the field that alienated pretty much all the english/other euro language guilds. I’m glad to say that the move to Gandara has revitalised the guild and that we’ll be sticking it out in there.
On the flipside of things, the shift in players has left space open in the lower tier servers for new guilds to fill the space. A guild member who chose to stay in BT tells me that a number of WVW oriented guilds have joined BT so who knows, after this period of chaos there may be a change in the winds
