Like one of the main points of progressing and leveling up in an mmorpg is to be more powerful overtime, and enjoy that powercreep with older content. All this constant nerfing is just not fun, and really kills the enjoyment of the game, and is definitely not play how you want.
Alot of these changes dont even make sense, you have nerfs one update and buffs another that go back and forth that just confuses and pisses off players with the constant changes for no reason, not to mention the ever growing graveyard of sets. There is a serious disconnect with what players are actually doing, and trying to optimize against a spreadsheet, and making everything bland. it really feels like eventually we'll just be left with something hollow like vengence pve, where we have 8 classes and 3 roles to choose from, all so that spreadsheet can be optimized, but insanely boring.
Players dont want damage sponge bosses for the sake of prolonging a fight, or invuln phases where nothing is happening. Players want to play and experience interesting and challenging mechanics. like how many players never get to experience interesting mechanics like bahsei hm which is a 4 year old trial, and lose out on experiencing that interesting fight?
The developers are always trying to target that top 0.1% of players that are coordinated and optimized enough to just skip through certain mechanics, but it is such an incredibly small # of players that these nerfs probably wont affect them much anyways, but has huge dampening effect on the remaining playerbase which makes the game less fun.
Like players getting a trifecta, who cares if they do it fast? thats the whole point of the leaderboard where they compete with other teams. Why stop players from optimizing? it's like people who speedrun games, are you going to totally update and change your game to make speedrunners take longer that has a negative effect on 99% of your players? or let them speedrun and compete amonst themselves? It's like they have some irrational hate against player skill, and want to keep it artificially dumbed down for some reason.
