Thought I'd just make a few comments:
1. The spawn system is an issue for me, I mean fair enough if you get killed straight away when spawning on another squad member, but that shouldn't be possible when spawning on an objective, like in Conquest. If there is an enemy on/right near the flag you shouldn't be able to spawn there.
2. The hit detection is still a little iffy, that might be due to the ridiculous lag I've been suffering this afternoon though.
3. There just isn't enough maps, and there most certainly isn't enough game modes to make up for the lack of maps. They may be big, and I do enjoy them, but there's just not enough (PS. This is with the Limited Edition version of the game also).
4. The 'shooting from the head' problem is bigger than in any other game, it's so ridiculous when somebody is behind cover, I can only see their dome and yet they can shoot and kill me.
5. I know it's part of the BF experience, so this isn't so much a problem, but tanks make me want to snap the disk at times. Maybe there could be a lobby where no vehicles are present that is separate from regular?
Despite these annoyances, I've found the game incredibly fun and have racked up around 6 hours of play time so far, but it most definitely isn't going to be a game I can spend more than 10 days on like CoD because, quite frankly, it doesn't have as many match combinations.
