My experience in BF6 and feedback.
This is my experience from BF6 and problems I spotted while playing for 15 hours+.
First was recoil, it feels like all guns have nearly the same amount of recoil with little variation between guns and gun shots but also after stopping shooting it automatically goes back for you though most battlefields do this, but it feels too easy.
Second is the pace of the game, it is too fast for a battlefield, in previous battlefields gameplay can be fast in parts but not everywhere. In BF6 it feels like they are trying to copy call of duty instead of just doing what battlefields are/used to be. Map size is also too small for conquest which makes it faster paced.
Third is destruction, there is not enough. I was expecting entire buildings to be levelled like in bad company 2 but it's just certain parts like walls, front of buildings or the floor on the conquest point in Iberia. It was a bit of a letdown expecting what the trailers and the video with people talking about the game showed and talked about but i can get used to it as it's slightly better than BF4 handled destruction apart from the shanghai tower. Also, it should take a little more damage to destroy parts on buildings.
Fourth. Weapons need a bit more balancing which can be understandable as it's a beta. They should do more damage and should count like games like insurgency: sandstorm they do more realistic damage. RPGs can be shot near enemies and do 10 damage or C4 blown up right next to an enemy and doesn't kill them does about 10 damage as well. Also, weapons should take longer to swap and draw especially sniper rifles and machine guns and rpgs. Reloads should also take longer and be slowed down especially for machine guns and rpgs. Repair tool should repair slower to prevent them becoming invincible when you have two engineers repairing it at the same time.
Fifth is Classes. Classes should be locked to their weapons all modes should do this and not have it split with closed and normal modes. Normal modes should lock classes to their weapons. Assault should have the second primary weapon removed and med kits returned as in previous battlefields and supports just have ammo not ammo and med kits.
Sixth is Vehicles. They do not handle very good. Especially flying vehicles.
Seventh is movement, Crouch sprinting is a bad idea and not at all even realistic or like battlefield and the movement seems too fast more like super soldiers should be slowed down. Fall damage should be a lot more you can jump out a window at 3-storeys and receive no damage.
Eight are maps. The three maps for the beta are too small for conquest, they should be about 1/3 bigger which will also slow the pace down back to normal battlefield pace.
Ninth is multiplayer. While cross-play is great console and pc players should have the ability to turn it off as aim assist is too strong making it unfair for pc players. Aim assist should be a nudge in the right direction and around the player not directly on them so it turns into aimbot.
Tenth is cod influence. You can tell MW 2019 heavily influenced a lot of the gameplay while it was a great game and my first cod this is battlefield not cod. While also playing a lot of the sound are directly copied from cod MW 2019 as you can hear when navigating the menu or beginning a game. Even the starting animation on matches is influenced by cod too not just standing and waiting like previous battlefields.
Lastly. The graphics do look good but the game is not well optimized with one of the top gaming pc's you can buy which in my case is MSI Godlike Z890, Intel Ultra Core 9 285k, RTX 5090 and 4x Corsair dominator titanium DDR5 48GB at 6000 MHz because with full graphics with vsync on and frame rate limited to 144 with no anti-aliasing and no frame generation I get 60 FPS with plenty of CPU and GPU left as my CPU runs at 50% highest and GPU runs at 40% highest it should be maxing it out but it just isn't.
Overall, it's a lot better than BF 2042 but far off being good enough to be sold at 70 euros and more like a call of duty (not a bad one) than a battlefield. Please EA listen to your players they know better especially battlefield veterans. This is a beta so a lot can change but I think a lot needs to change, this is just my experience and opinions, but many others would feel the same.
Some parts may be added/updated over time as I remember these things or discover new things.
