I'll add my 2 cents here.
After playing the private beta, the 2 gameplay related issues that stood out to me were :
1. What is the deal with the new mod system? The bonuses and minus of each often felt random, as if they didn't made any sense, the combination of some of them. Also, I'm not sure if this was only because in the beta the gear was of the early game but often the negatives of said mods were so negative, that I ended up not equipping any. It also made it extremely hard to keep track of all the stats. 1 piece removed 15% crit chance, gives reload speed, the other one gives 15% crit chance but removes effective range? Do that 4-5 times + the weapons perks and all. Heavy stuff. Having lots of control is great but when its hard to keep track of it become a chore.
2. The skills (maybe again its only in the beta) were all a bit too "player controlled" ? I mean, it is great that you have the option to target your skill, but sometimes it was quicker to shoot the NPC than to try and activate then aim the bomber drone for exemple. Maybe the skills don't feel rewarding/powerful enough to justify spending time to control? Turrets were great in the way they are activated and all, right of the bat they are autonomous but when you need to focus you can easily do that with the push of a button, great!
Anyway, just my thoughts. I'd be really interesting in seeing a post or a livestream addressing the community to update us as what feedbacks were taken into accounts and will be worked on maybe? No saying my feedback it THE feedback, or anyone elses, but at least we'd know what to expect down the line.
