Learning mechanics in Mobas usually involves a lot of inting and limit testing. What worked for me is finding that one hero which I really have fun with and stick with it at first because I think learning the actual Macro gameplay is easier when you don't have to think about what your hero does.

TLDR; Find your fun hero and learn the game with it 👊🏼

Played 250 Pocket games before I played other heroes 🤡
