Use of smoke

Aside from people being stupid right after spawn, I swear I never see people use smoke until they've been shot and need cover to repair. I never see people use it as a distraction, misdirection, or just as movement cover even before they're shot at.

"Hey, here's this sniping alley that's a meatgrinder, should I smoke it to cross? Nah. . . . Oh, I died"
