Smoke: does it have to be opaque?

[MCab]

Smoke, especially from smoke dischargers, makes defense almost impossible. Especially with the Z key.

Here's what I run into: I'm on defense, I have inf and AT assets awaiting ambush. The opponent comes, z firing, suppressing my guys. Then it's my turn. My infantry and AT is suppressed to where they can only get 1 or 2 shots, after rallying. I let off one shot, boom, smoke discharger kicks in and the enemy tank is out of LOS.

I know smoke wears off and you only have so much, but it's almost killing the game. Any plans for changing this?
