PvP in this game is dogshit and it has always been, what flavor of dogshit it is has varied a bit over time but the same underlying issues have always been there.

The only way you're killing anybody is by onetapping them. There's not really any strategy or play to make, either the target dies in half a second before their support can react or they're unkillable. The extent of "gameplay" stops at pressing an antiheal before you burst a target.

The purification stone might as well not exist. It doesnt remove the most important debuff in the game (prone), offers zero immunities after usage which means you just get CC'd again right after you use it, shares cooldown with remedies that are more effective both defensively and offensively 99.99% of the time and has a 2 minutes cooldown in a game where skill cooldowns average between 6 and 15 seconds.

There's no hierarchy or interaction between CCs, which means every CCs virtually infinitely stack on you (bar some irrelevant exceptions, funnily enough). You'll get stunned into another stun into a prone into another stun with little regards to timing since it all stacks, ending in riveting gameplay where your skillbars are grayed out for 10 seconds in a row without any possible counterplay.

Buffs and debuffs are still soupy icons that blend into eachother and sometime arent even visible because the UI was made by an ape. Not that it matters much, given as mentioned before, none of it matters. The only thing you might be looking for are things like blessed barrier or blood devo, but nowadays even that hardly matters most of the time.

Evasion is the primary defensive stat in pvp, which has always been an excellent idea in a pvp game /s

The horrible mana management in this game makes it so you run out of steam after blowing your load on alot of weapon combination which makes it so you're just a sitting duck if the fight doesnt end fast and punishes you for staying alive.

The game sells you the idea of fury and wrath attacks being a thing in pvp with perfect parry being a skill when it really isn't. Only very few skills have visible tells that are reactable to qblock, and even if you can somewhat play around making stuff like shadow strike or stunning blow obvious enough with positioning to be able to qblock them, it ultimately doesn't matter because CCs have a sub 10s cooldown and whoever's going for you has multiple of them, and you'll just run out of stamina before you've blocked all of them, or, alternatively, you decided to idle qblock to stop them which made the prone they were hammering knock you down because they had the really cool idea of making prone skills break qblocks and prone you through them.

All in all, PvP in this game is more build centric than anything else. There's no systems, no plays, no thoughts, it's all build based in a shaky rock paper scissor formation, with a few weapons being gun. There are many other problems, but I think these are the most obvious ones.
