SO! Last day of the Beta, I'm gonna use it to deliver a review.
First off, this is my first Battlefield game since BF2, so I haven't been privvy to all the little changes they've made in between with 2142 and the Bad Company series.
Things I like:
I like the kit customization, and especially the weapon accessory system. I can really custom-fit my kit and weapon to my playstyle. I tend to favor mid-to-long-range combat, so I like throwing good scopes on my weapons, sitting back, and providing supporting fire for my allies.
Speaking of supporting fire, I adore the Suppressive Fire feature. My K/D spread isn't always super impressive, but I still usually end up in the higher tier of points on my team because of all the suppressive fire I provide. Keep the guy pinned so that he can't actively look around him and spot other threats, fun stuff.
I love the new features of the Squad system - being able to spawn on any of my squadmates makes it easier than ever to stick together and work together. Add that to the Squad leader's ability to mark objectives, and giving him and the squad bonus points for following that order, and suddenly teamwork is much more encouraged. Now if only everyone who played the game would assign/follow orders, maybe this feature would get more use. Whenever I'm Squad Leader, I mark objectives that I'm going for, and expect my squad to follow me. 50% of the time, they don't. And I've yet to be on a squad where my Squad Leader assigned orders, and they never listen when I tell them to. Hey! It's free points! DO IT!
I like the scope glare on the high-zoom scopes, even the ones the assault rifles can use. I can see snipers a mile away now, so if my reaction time is good enough I can often avoiding losing my head and still have time to spot.
I like Bipods. No, I LOVE Bipods. The Support class is slowly becoming my favorite, if only because Bipod + 4x Scope + PKP = Machine Gun Sniping, which I am VERY good at. People forget that the only reason the MGs are inaccurate is the recoil - manually fire your shots one at a time and the gun is as accurate as a rifle. I've out-sniped actual snipers with it, no joke. LOVE the PKP.
Engineers get Anti-Air rocket launchers. Best. Decision. Ever.
Destructible environments are FUN. Learning what can and can't be blown apart with enough effort is a game in itself. It's just as exhilarating to blow apart a wall and kill someone that was hiding behind it, as it is to have the wall you were hiding behind explode, survive, and have to run like a beast to live. FUN.
What I dislike:
The inability to assign Fire Mode and Main Weapon to the same button, like BF2 did. In BF2, the default button for your main gun was 3. If you had your main gun out and pushed 3 again, you switched fire mode (single or burst, whatever). In BF3, if you manually assign them both to the same button, yeah, that still works. BUT, if you have a different weapon out and push your main gun button, it ALSO changes your main gun's fire mode at the same time. So I have to get used to having a different button for fire mode changes. Meh.
Oh my GOD, everyone needs to chill out with the fucking Tactical Lights. I've been blinded more by allies than enemies with the fucking things. I understand the appeal of them - if you blaze around a corner and there's a guy there, chances are you have a split-second advantage as he gets blinded and is shooting erratically in your general direction. The downside is, PEOPLE KEEP THEM ON ALL THE TIME. This ruins the element of surprise! The guy around the corner knows you're coming cause your dumbass light is bobbing along on the opposite wall! He can even judge your distance by how big the light is, and start spraying bullets just as you peek your stupid head around. Use the Laser Sight, it's better, and does the same thing - you look right at it, it is disorienting, but it is smaller and less likely to fuck with your allies, and you don't give your position away quite as badly.
A general complaint, people don't seem to like throwing ammo/health packs down with the frequency I would like. I throw my ammo kits down when I'm playing support, but because I usually find a good defensive position and stick there for that portion of the round, my ammo is mainly being given to allies who are nearby. Don't expect me to run to the other side of the map to give you ammo. My squad almost always has no ammo trouble, IF they're sticking nearby.
Looking forward to the official release!
