The launch was riddled with glitches, several of which have already been patched. A title update is coming (10/15), so a lot of the complaints you are reading should be resolved then. I've been playing it every night since launch, both solo and coop with a few friends, and I've been having a blast so far.
I truly don't understand the mtx outrage over this game? It's not like you are forced to fight other players with much better gear than you (PVP has a loot-level cap in place to normalize damage). So people are basically upset about the fact that their friend who spent $10 can kill ads slightly faster than they can. I have zero plans to spend real money in this game as I can unlock everything by simply playing, and I prefer the gratification of earning something properly, vs. just buying it.
Some cool things that make this game stand out to me:
1. There is a thermal equipped UAV that can basically always spot you unless you drop into prone camo (covering yourself with snow or mud to mask your heat signature). I panic a little bit every time it flies over me. If you are spotted, you get a pretty tough fight dropped right on your head.
2. You can't just run down a mountainside. If you do, you will wind up barreling down, severely injuring your character on the way. However, if you carefully step down a mountainside in the crouching position, you can navigate down pretty much any incline, even very steep ones.
3. Severe injury seriously limits your mobility, forcing you to find a spot to patch up your wounds before continuing on. If you wrap a wound yourself, your character walks around with the bandage on for a pretty long time. Of course, if you have a friend who is a medic, they can suture you up properly on the battlefield.
4. Sniping is extremely satisfying, especially when you pull off headshots from 350-400m out (you'll want the sharpshooter perks for this). Quickly pulling off 3-4 headshots in a row to wipe out an entire squad before they can even try to hide is always a nice feeling too.
5. Each enemy base has a unique layout which forces you to recon them before running in guns blazing (unless you really want to have a hard time). Yes, they reuse some of the building designs, while many of the bigger buildings are unique. You will be navigating old cold war bunkers and tunnel systems one minute, and fighting your way through Jace Skell's contemporary hillside mansion the next.
There are other elements of this game that make it stand out, but I think this is enough to show that the game is a lot more than just a cookie cutter shooter, like so many reviews would have you believe. My suggestion is if you typically like ubisoft releases (Wildlands, The Division, Splinter Cell, Assassins Creed, etc.), you are not going to be disappointed by this one.
