I don't care that warrior is a better tank in certain situations, that's ok by me. I do care the job I want to play is excluded from groups because of the timed chest.
It's bad enough we have partys of 5 monks, a warrior, and a few white mages dominating certain fights (fist of fire).
Here's an idea SE, reward a group for taking a more difficult route and nerf the drops for these cookie-cutter groups. Right now you got it ass-backwards. People that want to / enjoy a more diverse / difficult set-up are exiled.
