Here are my suggestions for the Enlisted Devs:
Improved Netcode - Trades need to go (especially at short range) as well the fact that you can die and then see the enemy shoot you.
Less botty bots - The AI soldiers need to be less snappy on ranged targets and respect visual cover. That said, they need to be a bit less stupid at close range.
Teammate name display - Teammates names need to be displayed over the head of their controlled soldier. This is good for both team play - “Bob, there’s enemy to the right”, and reporting the troll that just turned your squad into pancakes with his tank.
Improved “Who Killed Me” display should tell you if the enemy was AI or under player control. A cheat-like action from a bot is fine, the same from a player is less so.
