I think without a bunch of people to play with I'd have given up now due to the lack of things to do once you're equipped. Looks like they've already addressed the lack of seeing animals (seen 2 since starting, ran away from a boar, did get a nice headshot on the deer though). They need zombies to be more of a threat and we need to see more people, encounters are super rare from my experience so far. Higher server populations are needed or maybe just having vehicles will help with that?
Desync does need sorting quite urgently, you only need to run along a road with your team to see them warping all over the place.
It does look like they seem to be on point with patches and content so hopefully this becomes as good as I think it can be.
