So just the other night with my near full hc geared rogue i 1 shotted a full pvp geared warlock, which got me thinking, in arenas your gear is getting scaled down but say you go for 5v5 with 5 combat rogues, and open with cloak+killing spree on one of the enemies, my theory is that it could kill him without healers being able to keep up with the dmg, then after killing spree you vanish wait for cd and open killing spree on the next person, rinse and repeat.
What you guys think? would that work?
