I play Vainglory. My current, favorite hero is Petal (I know...maybe I have a soft spot for cute, cuddly, somewhat deadly bunnies). I used to play with Koshka but I'm not good at measuring my risks and usually end up dead :P. As Catherine, I overextend too much and depend on my tanking too often.
Ringo isn't bad, but Petal hits targets further away and I like her healing Bramblethorn seeds (return to base less often).
I think Krul would be a fun character to own though, and Adagio has always been one of my favorites.
Owned Heroes (in order of purchase): Koshka, Catherine, Ringo, Glaive, Petal
I've got my eyes on Vox as the next one I'm adding to my heroes list. :)
