For this boss it's fairly simple, just stack and burn. It does a throwback sometimes and put a dot on a random person witch explodes and kill any players near by (just need to go a bit away from the other players)
wow - that someone play this is unreal, standing still for 20 min doing nothing but click a few buttons to shoot......I guess if that makes you feel good and you made something, your standards is lower then mine!
haha yeah, world boss is not the most exciting with a ranger xD It's more exciting when going against groups of mobs where you need to be a lot more strategic
