Sorry I have been mistaken. When you go in it's with b2, or f3 combo, you almost never use f2 combos (biggest damages) even to punish (however you may use 1, 1, 4). But despite that you mostly use charge, even when you can free combo (maybe stress).
Against kitana, when 16bit is jumping in front of you throwing a projectile over your head, you used charge instead of db1.
I mean, compare to Blackula, you mostly try to stay as far as possible except when you are fighting weaker than you. So here was my question.
