Champions similar to heroes in HotS

So I've played a variety of MOBAs but recently I've been playing a lot of Heroes of the Storm because my friends are all Blizz fanboys and because I liked the short game more action packed brawl of it. Any way I'm getting tired of it and looking to get back into League. One thing is my favorite heroes in HotS are Kerrigan, Diablo, and Muradin. They insanely fun to play to me and honestly the only reasons I still play HotS on my own.

To all of you who have played both games, what champions are most similar to these 3 heroes?
