You can easily add an artificial "50ms" latency to the local server to simulate the internet.

You can also set frame limit to 30 fps to understand what people endure through in consoles.

Now invite a group of young gamers(17-27) to studio to hold a casual tournament, monthly or whatever...record the sessions and analyze!

There you will end up with a much better console version.

For the pc version, you can speed up the game's engine upto 1.2x to compensate for the readibility of the attacks to avoid the "turtle" style gameplay.

Other than that, you should acknowledge that the "Guardbreak" is not the (square/X)any more. Some people with a bit of sense change it immediately, others unfortunately trust the developer's sense and keep it like that and at a huge disadvantage against people that have scuff-like controllers with extra paddles at the back, cronus max'es, Xbox elites so people can avoid the " GB" while still able to use the "guard stick". The days of "either you are guarding or looking out against a throw" are gone. So you should either prevent people the escape the "gb" while the guard stick is in use( you should not be able to guard break while pushing the right stick to the left or right etc.) Or change the default to L1/LB and reduce the break window.

On pc version at the moment, people go against opponents that play in 120 frames or even more. That should not happen in any competitive environment.
