So what happens to a DPS that is trying to get a certain DPS item but happens to be the unlucky one with a tanking offspec and is chosen to do that role during the fight. How do they get they, the person who bit the bullet for the raid, end up getting rewarded? They end up with a +100 on their tanking roll I'm not saying I don't like the system but it is flawed when put into raid context (where it would be fine for 5 mans). I'm sure that will be a source of plenty of drama unless something is added where an offtank can state which item set they want before they pull the boss.
