70% of this game's PVP is fixed by adding diminishing returns
Players shouldn't be able to get 30000000 movement speed or 5000 damage just off rip. The game has a terribly unhealthy meta with backhits that enforces high speed high apm builds as the best because there aren't any defensive options. You just get absolutely destroyed because the numbers are more inflated than a DeviantArt page while they fish for largely unreactable sequences that IGNORE your defense.
Tone everything down. The combat is horribly volatile when it needs to be methodical. People can get too much ether/regen and cast too many mantras. People can get too much damage and deal 50% of your health for missing a singular parry on an Eruption Flame Blade and you get true UNVENTABLE combo'd into sightless beam. People can get so fast that you have to track like it's an FPS game just to not die. If we wanted to get really serious, then in actual fighting games you have damage scaling to prevent combos from just annihilating you. Almost every issue that people have with PVP comes from some number being too high.
The other 30% is from removing shaky block btw. The punishment for getting hit should be losing hp. It makes no sense to punish the loser for losing. Being in disadvantage is the punishment.
edit: I wrote adding but I meant enforcing
