1. Assault rifles are a tad under powered and have a bit more recoil than they should in long bursts. I know burst fire is the way to go and I do it quite often, but some situations pop up where you must go full auto. I like using the drum mag for a larger clip with less reloads and I can say about 15 shots in it starts going everywhere but straight, all I can say is just give about another 5-10 semi-accurate shots and I would be ok with it.
2. Game needs to learn when I want to slide, it only seems when I am looking right at the ground does my character want to slide and that is actually getting annoying.
3. Beef up the drognav SLIGHTLY. In no way am I asking for a one hit kill, but where it is on the board of power, SMGs can beat it out. Just putting it slightly past the half way point on damage could help it.
4. This is so much an issue, but personal preference. How about an extra shotgun or two? :hubbahubba:
Other than that, I love this game. Telling all my friends to buy it and for multiplayer it has replaced black ops. I'm only keeping the game for Zombies..... -wink wink, nudge nudge- xD
