My suggestion:

Practice with bots similar to fighting games (Street Fighter, for example). This being able to change the bots' general behavior (defensive, passive, aggressive), what it is/isn't allowed to do (block, parry, guard break, attack, etc.), whether it takes damage or endlessly respawns, which type of bot hero it is, how many bots there are, and which bots are on which side. All this as well as being able to do this while loaded into an actual game instead of having to constantly remake it.
