I'm not dissing D3 in ANY way by talking about this but I know there are League of Legend players here and y'all tell me is there any similarity to the skills from the Classes on D3 that could possibly be from League of Legends? Let me show you some skills that show you Champions from LoL.

***This is not intended for arguments against D3 because I LOVE this game. It's just funny how similar the skills are.***

Here's the list of "Champions" haha

And there are others like Teemo, Ziggs, and Yorick all from Witch Doctor but seriously Blizzard. Couldn't you have made it a little less obvious? =P
