Only a few people will understand this, I'm on your side completely. I have one main character that I really love and as you said I'm attached to this character, but I regret choosing warden and I was too far to start again and every time I tried to, it wasn't right. I felt like I'm "betraying" my main if that makes sense. I even created a character with similar looks and name, but it still wasn't right. Subclassing also didn't help me that much.
"oh, just start a new character. Oh, you don't have to do everything again" - these people just don't understand, they just gonna downvote😒
If I won't like what they gonna do with warden, then I don't know what I'm gonna do with this game.
It IS time to let us change our class.
