First, I'd like to start off with the good; all the little things really make this game stand out. The panicked breathing from a grenade in close proximity...counting your kills under your breath as Recon...the dynamic weather storms...it's the best Battlefield I've played yet. The destructibility of the environment is great, and the gun-play is excellent. The maps are designed well, though I think they could be larger...Panzerstorm was a very nice addition.
There are some things I would recommend adding/changing though.
Suppression - Feels very weak/useless. As Support, I feel as though I should be able to rely on suppressive fire to allow my team to get from cover to cover, or pin down an enemy...but as it is, it just paints a target over my head and leading to me dying shortly thereafter...usually killed by the enemy I was 'suppressing'. I am unsure what to recommend other than making the Suppression effect more intense, as right now it doesn't suppress anything.
Bipods - For the record, I haven't used bipods since the last big update...but my prior experience with them can be summed up with one word....frustrating. They are very finicky, and tend to undeploy/redeploy from the smallest movements. I will often start tracking an enemy, open fire, and then a moment later m bipod will fold up, making my bullets hit nothing...resulting in me usually dying while trying to set up the bipod again. They're just unreliable, and it's horrible.
TTD - The frustrating death behind cover. Many times I have died thinking I had just made it into cover, to die a second later. Obviously this is a bigger issue than a simple fix, but this is one of the biggest detractors from the game.
Squad Size - Increase back to 5? I think it would promote more balanced squads and allow for some redundancy. Miss it from BF4 and BF1
Hardcore - Where is it? I long for Hardcore mode and hope it makes it's way into the game soon...
Rentable Servers - Where is it? I wish to see some Pistols Only servers again. Note: Please add the option to control weather with this......I would love to join/create a server which is guaranteed to be nothing but snow/sand storms.
Assault/Support Class - It might just be me, but I feel like some of the gadgets are a bit mismatched. Personally would prefer to see the Sticky Dynamite and AT Grenade Launcher gadgets switched. Also, I think the Engineer Combat Role should have increased explosives inventory. But that's just me.
Factions - It was disappointing to only see the Brits and Gerries at launch, but hope there's plans to throw in some of the other powers! I think the Americans and Soviets should be next priority....though I know many people want to see the Pacific theatre get some attention (everyone wants to go back to Wake Island).
Weapons - Would really enjoy some more weapon diversity...the more the merrier, you know? I think adding some more Anti-Tank gadgets would be awesome, like the Panzerbuchse 39, Panzerschrek, and the Bazooka. Also would like to see some infantry flame-throwers.
Class Weapons - I, like many I've seen, aren't 100% satisfied with the weapons available to each class. I think shotguns should be an all-class weapon, and Medics should get Carbines in addition to SMGs. Also, I think another all-class weapon type should be added, in pistol carbines, (pistols with stock), ie Mauser C96, Hi-Power w/ stock, Luger P08 w/stock, etc.
Browning Hi-Power - A bit nitpicky but why is there no Hi Power!? It was used by both the British and the Germans (as the Pistole 640(b)). I do sincerely hope it is added at some point, because it's a beautiful pistol that deserves some video game representation.
Additional Idea - New Gamemode....Epic Battles. Increased player count, more vehicles, larger map...could be something awesome!
