there is no such thing as mastering anything, you just have 4 buttons for abilities and wasd and auto attacks. the only thing you can do is use these abilities optimally, or play like a retard. cs at least has multiple options. you have grenades, different guns with different advantages. you cant only play 1 gun in cs. in moba games you can play only 1 character and never learn another part of the game, besides which enemy abilities you need to avoid.
its just super boring, one dimensional, there is no strategy aspect to the game.
"vision control" literally just means spamming wards on the map, omg such skill.
"wave control" means killing ai controlled super weak enemies with auto attacks.
the game just sucks, get over it. it is designed for little kids.
