I would love to go into every detail but unfortunately it would take me an entire essay...
I'll simply try to list the problems, all other things are just superb if not perfect.

- Decent/good online. They simply can't make that if one leaves the match, it counts as a loss. That is a huge disappointment and hurts very bad the multiplayer experience.
- Decent Main story and a really scenic and spectacular final battle. Very funny character episodes. The narrative doesn't really take itself too serious but it's really just too stupid, they could have done it better imo.
- Heat System is wack. All this "aggressive" direction of the game is fun at first but it hurts the competitive scene. This game is competitively dumb as fuck, like just mash everything oooga booga. Tekken was all about defense, now it's moronic. T7 was also going into this direction and everyone was disappointed. Good for the sales and I'm ok with that but now we're left with a monkey braindead game and they can't do much about it.
- Some bugs and really broken tools they need to adjust.

Don't get me wrong, I think this is one of the most fun and best fighting game of all time. They did an incredible work and they're going to adjust all that they can. I have faith in Harada and his team. Dorya!
