Put animation cancels in for abilities

1 - How is this game "for children"? There are many aspects of this game that require skill such as efficient CSing, vision control, counterpicking, counterjungling, invading, ganking, teamfighting, and much, much more.

If you think the game is bad then you're entitled to that opinion, but it is most certainly not simple.

2 - How does adding animation cancels improve the state of the game? In a MOBA that means burst champions would kill faster, the overall state of the game would speed up, teamfights would be more chaotic, and slower paced champions would suffer heavily.
