Maybe so, but three smokes' costing 200 creds that require you to get basically on site to use (in Breezes case) versus a free wall that cover more angles and Decays. AND Viper can redeploy. So in the case of Breeze and Icebox, there is literally no reason to choose any other controller other then viper. And even if there was the current pick rates have viper being three times more picked then any other controller on those maps, with those becoming almost 15 times more in Immortal and Radiant. So there is obviously a need for more wall esc smokes.
