Making it easier to play the game. Since they already made the combo system easy to use they might as well just make it easy to do special moves. Because some people will probably complain its too easy there should be a trade off. I say one button special moves in combo assist but also if they do do that they have to wait for a cooldown period like league of legends. Also showing a aiming reticle showing off where a projectile or special move will go like league would be good.
Tutorial needs a reboot explaining the difference between Assist and no Assist. Some of the things in the tutorial are harder in assist because of added hits.
Am recommending this because Riot, the creators of League of Legends, acquired that robot fighting game studio that used cooldowns. Only a matter of time before they release a league of legends fighting game with cooldowns making it so it seems revolutionary in the field of fighting games and becomes immensely popular.
