I have a right to focus on PvP, given that my experience as a Subtlety Rogue in PvP was outstanding for the entire game's history until it dropped off a cliff in Legion, and given that more PvE focused Rogues already had two outstanding specs to choose from -- did they really need to take ours so that they could have a third and we could have none? Again, it's a pure dps class with 3 similar melee dps specs. It's a complete failure of product management to design all 3 for PvE and let PvP be an afterthought, and particularly egregious given the history of Subtlety in PvP.
I have a right to be upset as well about the radical change of direction to my RPG character in which I've invested hundreds of days time /played. Even beyond the gameplay level changes, which are obviously terrible, there's the fact that they decided on a completely different aesthetic direction for a character class in which players are already heavily, heavily invested, to the tune of over a decade of subscriptions and hundreds of days of time in game. What idiot manager signed off on that without anticipating the shitstorm it would cause?
It's been 4 years since Legion released, and even longer since the change of direction was originally announced. Consider how angry people are still, years after the fact. Go over to the official Blizzard Rogue forums, where I am not active currently, and look at the sheer number of threads and posts by other people who are still angry at the design direction since Legion and feel that they have lost something important to them.
Also, Find Weakness was never just a damage buff for Shadow Dance. You could apply it with Vanish, Prep+Vanish, or manual Restealth as well. Oh, you don't have Restealths in PvE? Maybe that's a problem with the way combat flagging PvE works rather than a problem with the design of Subtlety spec.
And if pre-Legion Subtlety was a symphony of hit & run restealths to create FW windows, it was also a concerto of crowd control, utilizing your DR categories to your full potential to disrupt your enemies and create your moment to shine. Oh, but bosses in PvE can't be CC'd? So we need to completely redesign the spec, in a game with 35 other specs, to be YET ANOTHER generic "tab target and press 12345" damage rotation to make numbers appear on your screen. Yeah, I'm sure the existing audience is gonna love having their unique playstyle replaced by a generic "rotation" bot, but this one has purple spell effects as opposed to Ret paladin's golden spell effects, to convince the masses that it's still so different and unique. We traded a masterfully unique playstyle for purple particles. I have every right to be furious about that.
