I don't see the point of DOA anymore. The fighting system and balance is never deep for competitive level. We already have Tekken. In regards to fan service with the female characters well Capcom has jumped on that bandwagon so it seems there isn't anything left for this IP that make it unique.
As others pointed out, Tekken has nothing to do with DOA. The latter is also not unique just by TnA.
I mean, maybe you'd have a point if VF was still alive, but there...
I'd change it into more competitive style. Remove danger zones, remove the way holds can get you out of combos instantly and at least put a cool down on them so people can stop spamming them. I'm aware it's a triangle system and you can get a hi counter when you throw someone doing a hold but holds are way too easy to do and have next to no risk which creates boring as hell plays. Tune down the damn costume dlcs too and put more important things in the game. Fix the ranking system so that a rank a doesn't lose 1000 points for losing to a rank c just because he spammed holds. Am I bad for losing to holds? No, I'm not but it's really shitty that I learn big combos and one hold equals the damage I did. Fuck that noise.
I have no problems with the sexual characters but rather how they are portrayed when people want to play competitive.
Fair enough for the ranked system.
Danger Zones can be deactivated when choosing a stage though, it's not a game issue, but a tournament choice, a bit like Smash. Holds are part of the franchise and you can get stunned out of them, it's really not that easy.
