Well, 125 was too short for a battle mage IMO. I want to keep that feeling of ranged attacks but not being too ranged like Annie or Caitlyn.

About the crit, like I said some comments ago, it's because he already does magic damage with his basic attacks and deals to a single other enemy unit within range of the main target, 100% total damage. With enough crit damage, you could kill 2 champions without even attacking the second one. xP
