BIGGEST ISSUE - MAP DESIGN

You raise some good points there.
My response 

• Slower down gameplay a bit
  I agree the game feels too fast. But can't say why... I haven't played BF 3 / 4  in almost 10 years and don't have access to the stats. But if I remember correctly, the players movements were faster in BF3 and 4 and more fluid. Also the TTK there was fast. So I don't know that's the biggest issue here. I believe the total chaos of too many players on too small maps are the real problem. I don't have time to think because 4 other players are also shooting me form 5 different angles. Also it doesn't help if enemy can re-spawn without a real delay. 
  
  
• Closed weapons should be the only option
  Your right to ask the developers to make a choice. We don't want the player base to split up. But if they choose to keep the open weapon system, I have some suggestions posted here: Open vs closed weapons? | EA Forums - 12440854. I think it can be an evolution from the old closed system, but there most be bigger incentives to use the right weapon and penalties to use an other class weapon. 
  
  
•  Some classes are overpowered
  That's something I don't hear people say much, but is something I also agree upon. I think were missing a dedicated support and medic class here. But also the balance with the assault class seems a bit off.  I don't know why someone would keep using the recon class if thy can use a marksman / sniper rifle with assault class. There they have a second main gun, pistol and spawn beacon (if the change of the spawn beacon becomes a thing). 
  
  
• Map design
  Yes, this seems to be the biggest problem here. Maps that are too small (in the beta) with too many players on them. It become a clusterfu_ck so fast. The beta maps seems not only small, they have linear and doll designs, with flags almost next to each other and unbalanced choke points. I hope there are some better maps in the retail game...
