1. Denials don't feel fluid. I have a PS4 Pro and a monitor and most of the time still can't get the denial.
2. There's not enough information about the mechanics under the hood. The training manual only covers the very basics.
3. The sub system is nowhere near as good as UFC 3. It's all over the place when it comes to balance. I feel like if you brought back the old one - at least for the ground subs - the game would feel so much better.
4. Its hard to fight behind the jab and the jab is also hard to counter at the same time. I don't know how this is but its just me maybe. The jab is effective in combinations. Its not effective for keeping people off you or for intercepts.
Theres a great foundation here. The patches are making things better. But I feel like these are the key issues with the game.
