Few issues I've noticed:
Falling on helicopter's blades does nothing except act as ground for the person to run on.
Occasionally the consumables quick wheel won't let you select a different item and the consumable you do have selected cannot be used.
I feel the 150GS enemies should be much better at detecting people under level 20. I ran Panther and was almost never spotted as me and my team killed the entire 150 camp. 3 of us were under GS20 and the 4th was GS45. I'm not saying the camps shouldn't necessarily be doable at those levels, they should just be ALOT more difficult.
There was a waterfall texture near the Behemoth to the north of Erowhen in the Smuggler's Cove area that at the top of it the water animation was absolutely horrid. It looked like pin wheels of an 8 bit water texture spinning at the top of it. That's the best way I can explain it...
Another suggestion as the gearscore system seems to be a major point of contention, and it's hard to say if this is already implemented, but maybe give more advanced or high tech weaponry/gadgets as you get higher gear score, that way we're not just upgrading the same M4A1 over and over as the power level goes higher.

That's it for now!
