I didn't mean one-man it, i meant let a group handle it, like any other dungeon or raid boss in any other mmo.(then again, it sort of annoys me that they don't have raid instances yet, or a dungeon finder)
I also don't see how having players have huge amounts of power is a bad thing, the god of war games for example are fine, and wow ends up just fine while still letting groups of players kill even deathwing.
