Well, i am no pro in arena or anything. My highest ratings were always around 2k, though i am sure i could have pushed more if i wasnt too lazy. Ive been playing since season 1 (TBC), and even then warriors couldnt kill me in two globals. Then this happened to me the other day:
Just realized the resolution might be a bit bad.. Basically it was a 228k heroic strike, followed by a 160k execute. I am fully PvP geared and i had barkskin up at the time. :/
