dude that is an extereme spec isnt it? whats your max crit?
My Frostbolt spam is hitting for an average of 1250 or so. Double that figure on a crit, not counting trinkets or 6/8 Frostfire bonus or anything else.
I've got screenies of much bigger crits than that (trinket running/Power Infusion/Berserker buff/target was unlucky Warrior in Berserker stance/Curse of Elements on the enemy, etc.) going way over 4000 ... but those don't count. :)
