Just wanted to Add that I'm also in the Dota community and that's how I heard about Demigod. I think the initial interviews I read that made references about Dota were spoken well. I was left with the impression that Demigod won't be a retail Dota clone, but it is inspired by the main Dota mechanic of generally controlling one Avatar in an RTS type war and battleing through tons of creeps and enemies as an overpowered being with the goal of destroying your opponents base. It's something you can't really get in other games.
The devs didn't mention DotA, the interviewers drew those connections themselves.
DotA isn't the only game that has been taken for inspiration.
Not that we're saying "gtfo DotA players!" we're jsut saying it isn't DotA but we think you'll enjoy

And yeah, DotA is just another AoS type game. THere are many others.
