I like BF3, but I feel they should just can the UI/squad/etc system in entirety and copy what was in BF2 over. Not being able to just click on a spawn point is unintuitive, and it's hard to create and manage squads, whereas it was easy and made sense in BF2.
Also, the quick command in the command rose, it's nearly impossible for me to even hear myself if it's noisy around (it usually is), and I never hear anyone else saying anything. I thought it was a fluke, but messing around last night with my brother (he was across the room), he was spamming things like 'affirmative', etc, and I was literally 5 feet away and couldn't hear anything. That worked much better in BF2. They should also put a little screen indicator if someone in your vicinity says something like 'I need a ride', because it's just so hard to pick up on that in game.
I feel a little overwhelmed in the game really, so much audiovisual overstimulation that sometimes it's difficult to follow whats happening, but that's not really a complaint, more of an observation. It changes the game dynamic a bit from pure aim/strategy elements to more of how fast your brain can pick through the clutter to focus on important stuff. In many past games I would turn details down a ton to help reduce this kind of overstimuli, but BF3 seems messy under all settings.
