Mage: 18% Damage

[Rosulm]

Just gonna make it quick and to the point. As many mages know, if you have 4 piece t10, the 4 piece gives you 18% for as long as your mirrors are up. Well, because the 4 piece is a buff rather than a factor of having mages active, if you throw on 4 piece t10 before the tank pulls, pop mirrors, and throw back on normal gear, you have ~20-25 seconds of 18% increased damage.

Quite nice, but extremely annoying I would guess

My apologies for flaming but this isn't really an exploit and most mages should know this. It's the same as when you used 2p tier 9 to get the extra crit % from MA.
