Team Fight Animation

I know I am being a little bit overreacting as this is a very common problem in many games, but seriously. WTF. It is nearly impossible to pay attention in a group fight with all those damn "cool ass looking animation" going on. It is so hard to see whether an indicator is from Zac E or Xerath ult or Vel'koz E, and sometimes it is so freaking hard to aim a freaking vayne behind a bunch of malzahar pests(or simply just tanks with larger models). Try to find a Morgana Q in an ongoing group fight is literally the one of the most painful thing I've ever faced. Also don't get me started on Project Ashe : ^) I wish league has a change target shortcut key... Or does it exist but I am just too dumb to find out? Any suggestions of how to "aim" better?
