I find this amusing - not because OP is incorrect I mean I see his point - but I run stuff every weekend and weekends are the times I drink. Unless I'm completely floored RL theres literaly no issues in playing 'drunk', just like the very strange ability to always find your way home after a wild night, your fingers just do what they always do. IF anything - I'm a much more forgiving healer at the weekend, so dps in those AoEs all you like! Only difference noticed by other people for me is I tend to turn my mic off if i'm on teamspeak because no one wants heavy-breathing and squeaking about cats for a whole 2 hours XD.
Also - apart from Final Coil and Savage - theres literaly nothing ingame right now you cant get through by just faceplanting your keyboard and licking the WASD keys. The game is more about having fun with genuinely awesome people to me.
