I'd like a number of fixes / changes. Hopefully at least a couple will be sorted in today's patch.
In no particular order:
Kill Cam - being changed in the patch, but at present it's incredibly frustrating to be killed and not have a clue where the person was hiding (unless they were nearby). I guess this might be classed as "realism" but it's not much fun. In previous games, recons and the like would need to move around to avoid retribution. At present they can largely stay hidden in the same bush, or behind the same rock with impunity. Hopefully today's change will resolve this.
Spotting - I can understand the reasons for removing the previous versions of the spotting mechanic where pretty much whole squads and teams would be lit up under a sea of Tangy Cheese or Cool Doritos, but I think they've gone too far. I'd like to perhaps have a squad spotting mechanic whereupon any enemies you spot are highlighted to your squad, but not the whole team (and keep the system where the marker is lost if the target moves out of line of sight).
Enemy visibility - I never had a problem seeing enemies in previous games, but they can be like chameleons in this, blending in perfectly to rocks and the like. Maybe I could slow down and take more time surveying the surroundings, but by the time I've done that I'll have had my head shot off by someone practically invisible laying prone on some debris.
Supression - bring it back ferchrissakes! I'm sick of getting someone down to 20% health with a spray of LMG fire only for them to stand statue-like and kill me with the headshot they've been able to perfectly line-up.
Tanks - make tanks harder to destroy. It's somewhat ridiculous that a single assaalt can destroy a Tiger Tank singlehandedly. Either that or alter the assault load-outs so that you can't have rockets, dynamite AND anti-tank grenades equipped at the same time. At the moment, tanks have mostly become long range vehicular snipers because getting anywhere near enemy infantry is an instant death sentence for them. Given the power an popularity of the assault class with it's selection of short and long range rifles, ther are always swarms of them waiting to quickly destroy tanks.
Vehicle spawns - If you select a vehicle spawn, you should have a small window of time where the vehicle is reserved for you (maybe 5 seconds) to allow you to choose the tank or plane you want to use. At present you have to widly mash the button to get a vehicle before someone else and then accidentally end up in an AA tank on Devastation or something. Similarly, let us be able to selct from all the vehicles available instead of forcing a choice of just three in My Company. Firearms and equipment don't have this restriction, so why should vehicles?
Bipods not deploying properly - hopefully fixed today.
Getting stuck on small bits of scenery - this is particularly noticeable on Hamada on the rocky edges of the fortress. Likewise, not being able to climb unsteep slopes without sliding back down.
Map rotations - add the map voting system back in. If I never have to play Narvik again I'll be a happy man. Also, add DLC maps into the rotation. It'd also be nice to return to the old system for games like Breakthrough where you play each map twice - one as attackers, and then again as defenders.
Fix the "one-shot" TTD bug that makes it feel like you've been killed instantly without any hope of reacting by someone with a slow-firing Sten or something 100 yards away.
Get rid of My Company altogether and just have the functionality for that (and Assignments) avaialble via the in-game menus.
Despite all the above, I'm enjoying the game a lot.
