Difficult to MASTER yes.
Difficult to wing it? Oh hell no lol. I only played him like 5 times but he was VERY beginner friendly when mashing from my experience. He hits quickly, no recoil on his moves, and his moves hit at various angles. Aside from remembering to watch out for holds you can literally just alternate punches and kicks with him and hell keep thwacking away.
Yeah that wouldn't get me a win at high level but it doesn't disprove my point at all.
And you guys seriously gotta stop trying to just dismiss everything with "no your opponent just sucked" it makes you look desperate for an excuse lol. Even if they did, it has no bearing on Akira being easy to wing it with. He doesn't have awkward stances or anything like Sarah. His actual base movements are really basic, but surprisingly fast. He's just a lot of solid strikes. Only complicated when you try to go into setups and juggles. Fundamental though (which is all you really need in DOA), he's super easy due to his fighting style.
It does disproves your point because that shows you played people who are not strong at the game. You pounded a noob by mashing, that alone shows that the player you just played with are not strong at the game because it is already a known fact that you cannot victory mash with Akira.
You made an incorrect statement and it is difficult to convince you otherwise from a VF character that has a DOA model. To us "you" are desperate to exclude the VF characters as actual playing characters. Learn the game for once, there are no excuses, you are making an excuse to not deal with them. Your dislike just shows the type of player you are, there is no hope in convincing you so give up. Your requests with changes will never happen because it was never broke or unfixed to begin with. Enjoy.
