It sounds like people were expecting this system to be a class gameplay overhaul in addition to a system that merges all the disparate systems together into a cohesive whole.
I’m not sure that was ever the goal - in fact I strongly believe that it was not.
I like the talent tree system. System, specifically. Not necessarily the talents in it.
I think it should be at least considered if class design is in a good spot, because I would argue that it absolutely isn’t. Wrote about my most pressing concern here: Readability - an ongoing problem
