yeah i will totally be there 1 hour in advance and expect my friends to do the same if the blocks gets full, and an UQ is announced, not just scheduled ones, you cant go there, or if you are there in advance but you have your friends outside, then you have to leave if you want to play with them
....thats why there is more than one block with that same label, you dont need to be in the first one.
Multi-block search just introduces its own problems. Sometimes it just decides to not work and kicks you out to the lobby, sometimes it puts you in some dead block with one rando instead of a real group. The reliance on multi-blocking also has people using it at the worst times, like when restarting EQs. If everyone just hit "retry in current block" instead of multi-blocking then everything would go a lot smoother, the same group would largely end up staying together and be able to restart immediately, rather than waiting for a room to fill out.
