TL;DR: Play this game on your phone, not PC

This game has a lot of good things (from my memory as I haven't play PC version yet), various mission type, challenges, a lot of hero characters, well-made background, etc., however, this game lacks ability to bind units with hotkeys which make the game seems too awful to play for me.

I have played this game on iPad before and the game was a lot better using gesture to control, compared to keyboard and mouse. I strongly recommend to play this game on your phone/tablet instead of PC until this problem is fixed.
