I'm not a huge fan of the builds either, which comes down to there not being a whole lot of actual core abilities (not the skill category) as a basis. A lot of the legendary aspects are also pretty lame, so you kinda end up playing the same thing the whole time with not much development or tangible difference in effect. D3 at least had some crazy variations, despite being also a really weird skill system that I did not like, but so far not even the paragon board is really giving me anything but flat number increases.
My biggest complaint are the archery skills though. I typically main archers in every game that has them and I just don't like a single one. There's also basically just penetrating shot currently viable in regards to potency but it's also a weird skill & playstyle. Rapid Fire and Barrage seem and feel like garbage, and the two basic ones are probably the most useless basic skills I've seen from the all the classes that I've played.
Even sadder that I generally like the rogue aesthetic, since i generally prefer the sneaky rogue type archer over the more druidic ranger / pet class type stuff.
