If you think League / Riot is bad...
10 years ago Riot was a cringey startup making a DotA fan game. Today they are a multi-national giant with huge production values
Blizzard and HotS... omg. HotS runs like garbage on an average machine at low settings, HotS looks like garbage, HotS plays like garbage, every hero is completely unbalanced, character animations are shit-tier, design and concepts are like League from 2007 (perma-stealth, steroid-buttons everywhere, simple nukes that do insane damage), it's just self-aggrandizing blizzard franchise wankery. Blizzard has 100x the capital and potential to make a decent game and this is what they churn out...
The worst thing in league is still not as bad as most other mobas
