You can dance perfectly and be top dps ( which is not hard if you nuke the boss the entire fight while dancing, which is easy as hell ), it don't mean shit if the rest of the raid is shit and can't handle the adds.
So in such an event where the raid is about to wipe because there are too many adds up. If the melee dps don't go and help out on adds, just because they think it's more fun to nuke boss and be high dps, then they are idiots.
You misunderstood me, I wasn't referring to that part of your post. If the raid is being overrun then sure, it doesn't matter they suck, but you have to help them with dps.
However, I got yelled at even when adds were completely under control, there were never 2 waves at the same time yadda yadda. They just yelled and insulted me to go help on adds when they were under control and I was much more useful on boss.
