I'd say Bard, instinctively, and before anyone agrees/disagrees: I play as a DRG and moving is vital for many reasons in many fights in 40+ dungeons, so while drunk you can go in circles like an idiot and still actually manage to hit someone. You all talked about being efficient with the class...but I think the key word here is drunk. Yup. You can fuck around more with BRD, in my opinion which comes from no tangible experience since I tried archer only in Beta3 and I didn't really like it. But that's beside the point. Although to be fair, even DRG allows room for many of mistakes - hell, even MNK doesn't destroy a party with a single mistake. BLM/ACN are different, cause they are fragile and their loss of mana makes them useless or close to.I don't care about being a world first raider. I just want to be able to play semi-drunk and not have to rage if I miss a beat by 3/4 of a second.
I think that is what you call "my two cents". Hope I'm not making anyone mad.
