Free Step Dodge

I play Violet, backsway characters can still KBD in tekken, you just have to use a different method for inputting it.

Indeed they can. Still, compared to DOA...DOA isn't totally in need of such a method.

What about fuzzy guarding? Is that optional as well?

Well, in DOA it varies for character to character. Useful vs. Needed? It still makes all the difference in a match up. With Eliot I can KBD, make you whiff, and score a free 6p+k bound into dk for environment damage. Some characters have good options, others have shitty.

Fuzzy guarding is 50/50 for me. There are times where I would fuzzy after a safe move and I would duck a grab attempt or block a follow up mid. Other times I'd get thrown anyway because I did my fuzzy guard correctly but a player attempted a late bad throw punish. Something like that wouldn't happen in VF.

I disagree, KBD is definitely a good method of movement in this game. Most even at a tournament level don't use it because they can't do it, lol. Players normally don't know how to take better advantage of movement options in this game.
