Thief has been eating huge nerfs in PvE and PvP for a literal decade now. There's nothing left to say--thieves have given YEARS of great feedback on how to improve the class while minimizing the things people dislike about it and it's all been summarily ignored. For crying out loud, it's 2022 and Thief *STILL* has to trait into Trickery to get the initiative the class needs to function properly! That's something people have been complaining about since *2012*!
At this point there's nothing to be done. I decided a while ago to stop giving ANet my time and money. If you decide to keep playing the game, stop giving them your money at the least. Given the state of class and game balance and how many times they've promised to work on these things, they don't deserve it.
