This comment got me thinking. For how much could a fully tricked out level 60 mage crit, presuming he was a 31/20 Arcane/Fire spec, with that PI at rank 3 (40% boost) further boosting his/her damage.

I mean:
- Arcane Instability also adds 3% to damage and crit to the other schools afaik.
- Arcane Power gives you another 35% to damage.
- Power Infusion adds another 40%
- Zandalarian Hero Charm adds another +280 to regular damage.
- Talisman of Ephemeral Power adds another +175.

Then there are the rings, necklace, enchantments etc. The best of the best in short.

So how bad would bad be, if you got hit in this scenario?? Enough to one-shot a warrior in complete FR gear??
