No friends system would be a huge concern for me.
I don't have friends so I'm fine. 
Jomni do you have this? I have it now. I was rather impressed actually, never having played squad. Sheesh thier is a lot to learn and the community in my area seems to expect you know everything already... apart from sounding very mature, they seem to be much much younger than me
Grabbed Post Scriptum for the test weekend. Sound effects are great. Plays a little like a really small version of flashpoint, around the size we used to make our missions. A lot to explore here. Game I think has the right ratio of realism and practicality for a playable game so far. Here are a few screenshots off my PC so you can see what it looks like on a lower end PC. Was getting 40FPS, although at times it dipped to 13FPS. I am running an old 3570k processor and a GTX970 GPU and had most settings at the top, for those that want to know.
It's alpha and I am not sure when the next test weekend is. There were tonnes of servers full when I checked. Generally with 80 people or so in them
he mode I just played had an offensive and defensive side. Once the objectives are taken by the attacking player, one by one. They cannot be retaken. Only remaining objectives can by defended. This does not preclude a counter-attack but does stop that counter attack from actually taking back ground. In real life of course attacking and defending were most often the roles of armies at least locally. Meeting engagements did happen of course. I destroyed a Sherman Firefly with my panzerschreck as well as the infantry scout covering ahead. However because I was on my own, at an already capped objective. It was to no avail. In fact come to think of it, I do not even think kills are "literally" displayed in the points scoring system. It simply lists things like "teamwork" and "objective". This is a great incentive (not incentiviser) to work as a team. I assume if you stay with your squad you automatically gain points.
It really is a breath of fresh air to see terrain that trys to actually look like the area it portrays as well as undulating enough to make infantry effective at moving without getting immediately pinned. The fact that most players are forced to have their historical counterparts bolt action rifles helps in that regard. Tanks are very hard to see out of, although I only tried an British armoured car. You do see the commander of tanks unbuttoned, I imagine for obvious reasons.
