serene echo
long ago, before the smoke grenade got a big cool down you could generate an effective smoke barrage for a charge in Somme. Now the timing between grenades makes it pretty ineffective. Add a special ability that sends three smoke shells into the middle of the map - 1 approximately where aimed plus two that are quasi random. Perhaps have 6 registered spots, 2 of which are auto picked for the 2nd and 3rd shells. Smoke used to be a way to get a timid team to engage.
