I played a couple casual games and it seems ok.
The business model is not ideal for me, but it's way better than LoL in that you don't have to grind out summoners and masteries and rune pages just to have basic functionality like being able to jungle etc.
Technically it is impressive, looks great and runs very smoothly on my phone(nexus 5).
General movement seems a bit slow(basically every heroes base movement feels like CM without boots), but understandable because of the control scheme. Getting used to last hitting without blocking the creep health bars with your finger is tricky, might be better on a tablet though.
Apparently the people playing casual games on this have mostly never played a moba before, constantly people just running into towers and stuff.
Gameplay balance seems to inherit all of the worst traits from league. Items are mostly stat sticks that get better and better the more you upgrade them, ranged heroes have infinite kite potential, utility and CC are grossly underpowered relative to pure stats.
All in all not the worst game I've played. Better technically than LoL, and more interesting to play than HotS. The controls work great aside from the aforementioned blocking of healthbars while last hitting.
Hero pool seems a bit limited at the moment, but it's only a 3v3 game, so you don't need as many to fill out the teams.
