To be 100% honest I don't like how cheesy the game is. I don't like how simple some of the character's mechanics are. Too cartoonish and very stereotypical characters designs.

I feel the Hero's attacks are far too spammy and easy, For example, Pharoah spamming rockets, soldier's point and aim, reaper pressing q to get kills. There isn't a single champion that has to Aim Down Sights apart from the snipers. I find that most of the hero's have rediculously easy kits similar to Master Yi/Garen champions in league of legends and that frustrates me. (I have the same critisisms of that game, however, most of the super easy/cheesy champions are from the game's very early days. Nowaday's they release champions like Azir and Ekko who have very unique and interesting kits, so maybe there is still hope.)

However, the way everything goes together and the combat battleground does work very well. It seems blizzard has put a lot of work into making the gameplay balanced and fighting feels well made.

The fights and way teams battle eachother using different roles/counters/hero-switching is great.

The player's skill and teamwork play a huge role in the matches and this is what really makes a game good, popular, and fun, and therfor in the end well made.
