I know I'm opening a BIG can of worms here, but I would assume a patch is coming at some point. Here's what I've seen so far that I'd like to see resolved:

1) Migrating host issue that kicks players from the game, resulting in losing all XP for the given match
2) General lag issues where everyone is a red bar except for the host (which sometimes leads to the migrating host error that boots you from the game)
3) Texture popping - when spawning in, I've seen whole buildings not showing and then suddenly appear, as well as weapons where you can see the top attachment but not the gun (but it does load after a few seconds)
4) Anti-aliasing, not sure if they can fix this one with the limited hardware but some texture smoothing sure would make it a lot easier to see cloaked enemies. I don't know how many grassy knolls I've looked at thinking it was a cloaked enemy
5) Weapon balancing - subs should beat most guns at close range, but not at range...shotguns are way too powerful (1 shot? I could see that if it wasn't my foot that my enemy is shooting. Isn't that why I'm wearing an armored kick*** suit in the first place?). The predator bow seems inconsistent, and I've had several shots where the enemies arrow passed through a solid object to hit me.
6) ***Better team balancing*** some matches work out ok, but I've been in matches where no one is party'd up and our team will get destroyed......like 100-27. That doesn't seem like it should be that way..
7) Spawning - for the most part not bad, but when I kill a guy and then he spawns right behind me to get his vengeance, that's pretty infuriating...especially when it happens over and over.

That's what I'm seeing in MP so far. ***And this is meant to be constructive feedback so it can help the devs to streamline the online experience, not to trash talk and show how much of a hater someone is***

Matchmaking, hit detection, server migration and I'm happy as a pig in ****
