It still had the BF2142-old problem where you're utterly gimped starting out because you haven't unlocked your basic cards yet, meaning everyone but you's already packing grenades thermal detonators, jetpacks and personal shields, and all you've got is your blaster.
I also had some really bad luck grinding Drop Zone rounds starting out. Never won a single match, especially because some of the later games had some serious team stacking. 4v8? Really now?
However, the basic gunplay feels pretty fun already. I actually kind of like not having to worry about limited ammo, just recharge rates and overheating. Really suits Star Wars to an extent.
As for audio, the sound design's great, but stereo/headphone mode sounds...flat and one-dimensional. I'm disappointed when coming from BF3 with Enhanced Stereo Mode. Consider a sound card with virtual surround a must for SW:BF3, because it really does sound better once I put it to surround and let CMSS-3D Headphone handle the mixing.
Anyway, what I really want isn't even in the beta: DOGFIGHTING. SPACE. BOARDING ENEMY SHIPS. The stuff SW:BF2 already had, you know?
