Unless it is a critical lack of dps (read: certain afk behavior), as long as they don't make you wipe, you are all good to go. Nothing makes me cringe more than recruitment messages that read; 'low dps will be kicked'. Note this is a farm group, and while I understand that you want it to work out, a guy sitting on 1200 can still make you wipe or getting himself killed because he refuses to move to avoid damage. I once had a group with 2 monks and a dragoon (M4 it was) and they were whoring for dps so bad that we wiped every single time. Not because they had low dps, au contraire, they just refused to move for certain mechanics. Once after 3 wipes we had to dimiss a bard because he just couldn't play and we couldn't clear the last boss in the dungeon. And many a time did I dimiss another healer or tank if they didn't do their job. So it is up to you guys to make the game work, not a meter.
