Hey there!
I'm still pretty much on the fence about whether I want to play SWTOR or not, but for now I'd still like to understand what you're asking for here...
Why do all the LGBT guilds need to be on the same server? I'm assuming you're not implying that there should be a separate server *just* for the LGBT community, 'cause obviously that would be a very bad thing. Of course everyone in a particular guild need to agree on which server to operate, but why ought *all* of the LGBT guilds be forced to be on the same server? Surely this can only lead to people restricted to playing in a certain time-frame being potentially unsupported? If there are enough people who want to play on server X and want to play together, then there's no reason why they shouldn't have their own fleet there. And if there isn't enough people to warrant this, then they'll naturally gravitate to either another guild in their time zone, or one of the LGBT guilds on the other server, according to *their* preference.
So why is this a Dev issue? Once a fleet has chosen which server to play on, it's simply up to the players to join the appropriate server in order to play with their fleet. What exactly are you expecting from the Devs?
