Well, is there really more choice though? I guess in a very literal sense that’s true since before you only had a handful of tier and you could only pick one talent per tier and now there’s is a whole tree and you get to pick dozens. But that’s where the fantasy ends and the reality strikes you like one of Raszageth’s lightning bolts.
You quickly realize that it’s an illusion of choice, with many of the talents being previously baseline ability functionality that got broken up into individual talent nodes (Arcane Barrage is the perfect example of how they did that). Virtually everything else was a copy and paste job from SL’s covenants, conduits, and legendaries which were arguably some of the worst iterations of the borrowed powers system since its inception back in Legion.
So yeah, trees are better than tiers but not when the trees are made up of a separate node for the ability itself and then half a dozen other nodes that incorporate its previously baseline functionality and others which give said ability boring damage increase buffs often by needlessly over-complicating and bloating the base rotation.
The whole talent tree revamp leaves me with the impression that they actively tried to spend as little time and effort on it as possible and that’s plainly not a good thing. Especially when they have nothing else to show for all the resources they freed up by not working on any other expansion specific system in DF. I know I’ve said this before but I think it bears repeating. They barely did anything and yet somehow managed to make everything worse.
