i've done gold tank and dps as a dk tank (yes im a noob and did the dps one in tank gear because i have no dps gear ;_
but it's really easy, if people complain about doing an easy solo scenario that takes 10 minutes (literally) to get in a raiding guild, then just let them leave, they are A) not willing to put in work B) not listening to their guild or raid leader (whichever you are ) and C) if they honestly can't do gold .. they really shouldn't be raiding.. especially if you are looking for decent progression
