I feel that if Smite has an issue, it isn't that they are sexy but they are "cliche sexy". Yet another MOBA stacked with top heavy girls.
Dota 2 definitely has a lot of design so that all men/women/other heroes are different. Hell one of the females in Dota 2 is a god damn giant spider. Not a personification of a spider. Not a sexy humanoid dressed up like in a theme of a spider. She is giant, multi-eyed, eight legged spider that talks about drinking the liquified internals of anyone she catches.
