The mage does a 290k AB followed by a 168k AE.
The entire purpose of inflating numbers is to give people the impression of getting "stronger", am I correct in assuming that? So why not make Arcane Blast hit for 290 million and give everyone 1.5-2 billion health? Then people will get the impression that they're getting SUPER STRONG! Strong enough to solo Sargeras, all the Old Gods put together and kick over the Titans as the new ruling force of the universe.
All I'm saying is that this whole "woo I'm getting stronger" illusion is really silly. Just when Blizzard were discussing the item squish, they make the whole thing even sillier with numbers that will no longer fit on our desk calculators.
