at least 1/10 of my low attacks come out standing. It is the most infuriating thing I've ever had to deal with outside of this 8-frame move that pushes you out too far to do anything about on block and full screen on hit.
The mechanical inconsistency that breeds imbalances due to a lack of firm baseline of rules.
EDIT: Without claiming to be a coder, it is the actual core engine of the game that could have been developed better so that it allows for more elegant solutions, as well as the general design choice regarding move lists and fundamentals. Starting with armor, but we could mention the input bug or the infinites.
Some characters have no armour, and others have 2, 3 or 4 ex armour moves.
Every character should have just one armour move only. It's ridiculous how impossible some matches are in the absence of having no armour vs tons of armour.
Since all the obvious has already been stated. I'm going to piss people off and say dash jab combos, it's not even a real combo, dash 1, dash 1, dash 1. let the flaming begin. mwa ha ha ha
