Looking at the 12.0.2 patch notes, I can't help but notice that so many of the class passives, in particular the Nightblade masteries, all have drastic changes in their effects for PvP vs PvE.
I'm a returning player who has not played much since 2022 until a couple of months ago, and I've noticed a lot more sets and skills seem to have parallel effects for PvP and PvE, usually with some reduction for PvP or simply some effect or condition disabled in PvP.
While I understand that the balance of PvP is a difficult and controversial issue, and it is difficult to craft buffs for classes which are weak in PvE without having a drastic effect on PvP, especially for anything that could even remotely be considered useful for ganking (the canonically evil playstyle), I am really struck by how common this easy way out is becoming. Rather than introduce skills or modifiers or set effects which are balanced with both PvE and PvP in mind, there appears to more and more be a trend towards simply separating them entirely. The end state of this would be a game where you effectively have 2 entirely different ecosystems, with entirely separate skills and entirely separate item lists.
I don't think this is a good way to go, as should be obvious. I think part of the combat system that made ESO so much fun for so long was the depth of the one big pool of sets and skills and modifiers that all builds were crafted from, and how much variety and inventiveness it allowed. Delineating balance into separate pools by adding PvP specific conditions to so many options will destroy this and constrict much of the inventiveness inherent in developing builds, especially in PvP, which would in turn flatten one of the major appeals of ESO as a game.
I don't have much of a specific recommendation or comment to make beyond saying that I think it would be a step forward if there were fewer distinctions between PvP and PvE balance, not more, and if enough thought was put into mechanics to enable introducing things which are useful in both arenas without being unbalanced in either. I know this is possible because the vast majority of the stat impacting items (skills, sets, CP, buffs/debuffs, etc.) are still not touched by this.
