Sorry, I had a very busy past few days when I joined Fever. Waframe ahhh, I like that game quite a bit. My favorite frame would definitely have to be Ashe. Although Mesa is also pretty good. I'm currently building Nova tho and I think she will be my new favorite. (I play for PC also)
Right now my favorite is HotS because it has awesome characters like LoL (where I started playing moba's about 4 years ago) and there isn't the strange lull that is in LoL. As soon as you tell your character to do something it responds. Past HotS I would say Smite for the same reactionary reason, then LoL. I never gave Dota 2 a fair chance because I wasn't consumed by it's characters.
