Perhaps we should make a guild like this lol. The other night I made a SWTOR drinking game with some1 in general chat. I didn't write it down but I am sure we could do it again.
Unfortunately I'm unsubbed until they do server merges, and probably add their open space project that they're currently "working on" and will come "in the future" or I would definitely do it.
So I'd say really try and find a casual guild, by the extremely small chance you're Republic on the Krath server, I could point you to a really fun casual guild who don't really do raids and stuff, they just help each other out and form groups for FP or Heroics.
