I mean, I feel like this game could have a lot more freedom with even one more attack button, and more down-down specials (they have at least one).
Even without that, I still feel like it's a pretty good fighting game and easier to get into, but with that I feel like it could be one of the best, eh, "hyper fighters." More combo freedom (also I don't like Team Blue's combo limiters, but whatever), more neutral (or just pushblock distance and pressure chain) freedom, but also more intimidating when piling on all the assist and tag options. BBTAG 2, make it happen! Or... SG2...?
Oh, and air grabs. I don't really understand the reason not to have airgrabs; it's not strictly necessary, it's basically impossible to use Dragon Rush in DBFZ neutral, but I feel like it just hurts the rushdown of characters without really good anti-airs for their reversals since people can more easily jump sideswitch while getting walked (or ran) down. Chie and Yosuke have counters as their reversal action, and they are super rushdown. I get that just using fullscreen supers and calling assists is strong in this game, but there will (hopefully) be things happening at pushblock distance.
