Out of all the "Dota" inspired games I've played, this is by far the worst.
I'll start by saying this: You start out starting the game through the launcher, which is extremely confusing. You are staring at a screen with no clear indication of what to do next. You may be thinking that something as little as that isn't an issue... Well I personally felt that after the years of experience this gaming company has, that they should be able to make a user friendly menu and interface.
Anyway, on to the gameplay. At first glance, the game is beautiful and graphically appealing. I was very hopeful after seeing a lot of the effects of the various moves heroes can pull off. However, after a while I started feeling as if the game was missing something important. The towers in this game don't serve any purpose other than to prolong the game. They do very little damage as opposed to other games of similar style. Heroes are terribly imbalanced to the point of seeing everyone using the same 5-10 heroes out of a wide selection of at least 60+.
The worst of it all was the fact that the game does NOT match you up with other new players. I was put up against experienced players 9 games in a row, which leads me to the final complaint. The community of this game is beyond childish. It is downright disturbing. If you ever played Savage 1 and 2, well.... it is worse than those games.
Try the game out for yourself, but I recommend sticking with Dota or even league of legends. At least LoL is professionally well designed and sleak. No confusion and much more balanced.
