I know it's a Beta, a late release of a out of dated build that has bugs, which will be fixed. I'm asking for design changes, not fixes.
I've played Battlefield 2 for thousands of hours including the mods for it, mostly Project Reality. I can't think of any other game that would get me to invest so much time and effort into it. What kept me coming back was the team work; that sense of camaraderie I got when my squad completed an objective, or destroyed enemy assets. DICE's latest kick has been immersion, and I can't think of a better way to achieve that goal.
Battlefield 3 is a great game: looks amazing, remarkable sounds, and the weapon characteristics are outstanding. Now with that said, it's not a proper sequel to Battlefield 2 that the community was promised. It doesn't have a fraction of what kept me coming back to BF2 for hour after hours at a time. I'm not asking for a carbon copy, but retaining the features that made BF2 standout from the countless other shooters shouldn't be a big request.
I've been lucky enough to participate in the close Alpha test, as well as try my hand at Caspian boarder; I had a blast. But all of that's going to fade fast if the game doesn't retain those key team-play elements. Being able to properly cooperate with not only my squad, but with my team to win the game, not just run around mindlessly and find some pixels to shoot at. Here are some examples that I feel would make a great game a proper sequel that I've been hoping for:
Commander: I agree with DICE's decision to remove the commander role, but DO NOT remove the abilities. If DICE's motives for removing the Commander was that only 2 people were able to use it, then give it to the squad leaders, by removing the commander they've gutted a key element.
Squad Leaders: As it stands now they're just a special Dorito (Triangle with a star). They have nothing to offer their squad other than outlining the objective marker, which I would wager most haven't noticed. "Squad leaders can order artillery strikes, Troedsson said, and the ability to order a mortar strike is available as a multiplayer unlock." I hope that's the case, the game would benefit from the added depth. But I think if SLs had access to the Commander's assets it would greatly improve the game. I also hope SL have access to the SOFLAM as well.
Squads: You should be able to name, lock, invite/kick players. Only allow players to spawn on the SL, it helps keep the squad working together. As well as I feel the radio beacon, a.k.a. spawn beacon should be a SL tool as it was in 2142. I like the BattleLog, but it shouldn't replace such a integral component of the game, but accent it.
In-game VOIP: It's a requirement. You should be able to communicate with your squad at all times, even in a public server and a random player joins in. You should be able to communicate with others in your vehicle to be most effective. Squad Leaders should have their own channel in order to plan attacks, and setup defenses. Some of you may have heard of mumble, it's a VOIP client with in-game proximity chat. It's a great addition, you get a directional sense of allies, and it allows you to communicate with the whole team and it could be setup to teams only.
Customization: I love the fact they gave the players such a variety of weapons and attachments, it's going to keep it fresh and fun. But I don't agree with the vehicle customization. Vehicles without their counter measures, and armaments sucks the fun right out of the whole experience. I've seen quite a few videos of jets being spawn raped by stingers unable to avoid them without their yet to be unlock flairs. I've seen tanks unable to defend itself from a single infantry due to the lack of the machine gun. I welcome variety but when you take away key features I feel it has the adverse affect that they're trying to achieve.
Map: The current map is confusing at best, chic, but for purposes of conveying information it could be improved upon. Hate to beat a dead horse, but it ain't broke, don't fix it. Bring the BF2 map back, but improve upon it. Allow Squad Leaders to see other Squads orders to allow greater tactics and strategy. When enemies are spotted place their last known position on the map for a limited time. Let SL set waypoints, and reward players for following them, better than rewarding for being arbitrarily spawned on.
Teamwork Incentives: Make players WANT to be part of a squad, reward them for working together. An oldie but a goody from Battlefield 2142, bring back the field upgrade. You get your next unlock temporarily while on the server after your squad completed enough objectives. The squad perks were a good start but don't stop there.
As far as all the highly debated settings such as Friendly Fire, Weapon Damage, etc. All those things could be a server option, that would just enforce DICE's stand of play it your way.
Or at the very least release Mod Tools, and let the diehard Battlefield fans create their down ideal sequel.
TL;DR: If DICE added the lacking teamwork aspects it would turn the shooter of the year, into the shooter of the decade.
