The things they're actually looking for feedback on can mostly be adjusted by tweaking numbers and updating animation/sounds. And others are things that games like this typically update after release once they get enough player feedback. The reason for this 'alpha' is to get that feedback early so they know what needs to be adjusted. That way we get those updates earlier and have them based on actual player feedback.
Honestly, the only tricky thing on this list are the last 2 items. There's not enough tension around PvP encounter and part of that is no one is attached to anything they're carrying right now. But there needs to be more done there. And the AI needs a serious bump in aggressiveness.
Updates on Runners and their kit is something that would happen after the games comes out anyways.
This is not the first alpha test they've done, and I truly think they'll be fine. Whether or not the game finds an audience is a different thing.
