Also, 5v5, you have 2 mega nukes (shadowstep + killer combo) in total. Then repeat via Vanish.

So that's 3 v 4-box+1

And then your cool down is done; unless you managed to run away, out of combat and re-stealth.

What 5-man team wont be unloading dots, bleed. And don't forget hunter pets that keeps agro even after you vanish.
