ok so i'm recruiting for my 10man icc and i got a whisper from a resto druid, who has a main with 8/12 25man icc hm achieves and 10man, except he's extremely undergeared, i know there are people out there that are good even with shit gear, but how do you guys know if they are worth their salt or not, also with tanks as well not many are good at holding agro and i was wondering if anyone had any tips on how to tell them apart.
