It sounds like you have a lot of experience with crpgs in general, so I don't think you have anything to worry about. Since this is Early Access and not all the rules and such are present yet, the tutorial for the game leaves some thing to be desired, but hopefully that won't be the case come actual launch. There's definitely a lot of potential complexity under the surface, but as someone who's only played a little bit of D&D before, I don't think you need to fully grasp it ahead of time. It's stuff you can pick up as you play. Like feats are fun and interesting, but you don't need to deep dive into them if you don't want to, you can just apply ability score increases and you'll be fine.
