melee fixes are needed!

I have played this game for over 180 hours and have noticed a few issues with the melee in this game.one of these issues is the lack of parry in pvp and general melee balance if i were in charge of the balance the way I would do it is I would have the chainsword and knife have similar dps the difference would be the chainsword would be stronger and the knife would be faster and require more hits and with that comes more opportunities to parry the attack but it would be harder to parry because the knife is faster the power sword would be somewhere in the middle of the chainsword and the knife I would make the parry window exceptionally small so that only exceptional players may consistently pull it off.second I would redo every melee weapon other than the chainsword's combos because the chainsword has good stun options almost every heavy attack is a fast stun attack I would make it so every melee weapon would have a fast heavy attack like the chainsword I think this would make fights more satisfying.thirdly I would make melee stun attacks be more reliable not only in pvp but in pve operations as well, far too many times I ram into my opponent only for my opponent both player and NPC to immediately smack me down because the heavy attack I smashed into their face was shrugged off due to an oversight or something.
please fix.
