As far as stuff that's missing I hate that they didn't add the KV2 + a few other units fix to shell trajectories that allowed them to fire over shot blockers. It was a real game changer that made them a lot easier to use.
I really like Hector's idea of just disabling Rifleman smoke while they are suppressed. Fixes the worst aspects of Rifle Smoke (yolo blobbing into HMGs) but retains the tactical flexibility you need for pushes.
