The intent of this game, as far as I understand it, is to lower the barrier of execution and skill ceiling, not eliminate it entirely. Will a completely green player be able to land an AA BB combo first try? Probably not. However I am confident that they would manage to be able to hit it (or the much simpler and generally more effective Air B BB combo) within 5-10 minutes of practise. This game is also so face paced and has such high damage values that even if you can't hit the "optimal" combos, you're still going to be able to win the game.
I understand where your frustrations lie, but I also feel like you might be approaching this the entirely wrong way. If all you're looking for is a game that is 100% footsies with 0 execution involved, that game already exists twice over in the forms of Dive Kick and Nidhogg. This game is meant to be the in-between between those games and the more difficult games such as Street Fighter, Guilty Gear, KOF etc. From the start the intent wasn't for there to be no execution required, but rather to make it much simpler to be able to execute the longer combos in the game without having to spend weeks of grinding it out, as well as not having to worry about dropped inputs from your typical fireball/DP/charge motions.
Additionally asking them to remove a combo is simply just unrealistic from a game dev perspective, as doing so would require them to completely change the physics engine of the game.
