Which Haven heroes do you prefer?

I'll choose the one with the avatar I like more.

The hero's avatar? And this is a strategy? In my opinion, you should look at the abilities first, and then at the skills. After playing for a while and understanding the different advantages and disadvantages, everyone chooses the race/hero that suits them best, for their tactics and strategy. Also, it's a very simple fact that each race and hero has its own tactics and strategies. In short, you shouldn't choose based on avatars.
