1. I could do belts on normal on horribly geared 530++ alts without cloaks. And many were casters that couldn't maximize dps on belts.
2. Before you say I don't know what melee is like, just know I main a rogue that does heroic siege belts every week since months ago and we have a ret on belt duty.
3. Why are you getting hit by bombs as melee?
4. I suggest you l2p before making a thread to whine on forums. Terrible players get into terrible groups. People forming pugs who know their stuff look at experience over ilvl. The groups with many bad players are normally those that focus on ilvl.
