Get pro at Smash Bros Melee or Project Melee (Brawl mod). Until you're actually trying to do all of that, at that high of playing level. It takes years to get that good.

You have to make 3+ button command at an instant like they are all 1 button but you are pressing them all separately. Doing that every other second? That takes just as much time and discipline and time as a team of dota does to get good.

It depends on the game I feel.
