The request is quite simple really: to fully understand the motivation behind class traits and skills changes.
I've spent 7 years with skills and traits, which, to my understanding, have been working quite OK. Trait system was something quite original and deep. Now the move to skill trees seem like a strange choice. Skill trees (at least for me personally) seem to be something of an outdated design solution. They also push towards narrow specialisation (which also doesn't look good to me).
Maybe I could get an answer based on the opinion, post or explanation by the development team member(s), why this had to be changed? It would be important to understand the direction the game is taking (changing how all classes and their skills work is actually a huge thing, all people should realise that), especially with the preorder at hand.
Thank you for your time in advance!
