It is notable that actual versions of Normal and AI Control are pretty useless, because them don't reflect real arena fights in these days.
On normal test, our opponents have about 1-10k HP. They're simply defeated by one hit. This problem gets worse when using AI Control, cause you can't even see AI's behavior because there is no match at all.
As a plausible solution I suggest making both Normal and AI Control similar to Dummy Test: Infinite time and Infinite HP for machine. This not only solves problem about weak opponents, but also solves problem about power: Since we can draw the match at any time (see video below), we can simply draw several times and their power will grow as much as we want.
I'm not asking for an entire new feature that we could set opponent details, but just changing other modes to one already existing: Dummy Test.
