Yeah,its not big,but its not very little either,lets calculate what would you do with ulti + energy storm x2 ball hit on single champion with 500 AP.

(209.25+500x1.215)x1.8+(500x0.04)= 816.75 x 2=1633.5 magic damage.

So,an 209.25(+1.215 AP) dmg skillshot on 14 second cooldown,or 418.5(+2.43 AP) during ulti,not that "little" dmg.
