It's a nice entry level MOBA to the genre because of it's simpler mechanics. Doesn't add anything new to the genre tho, the only remarkable thing it's the franchise which is fine by itself if you are a fan (just like me).
Nothing great about this game but nothing bad either, the only negative thing I can think of is the lack of playable pokemon but that's only because the game is new and I suppose they will continue to expand on the rooster so it's not a big deal.
