How is this possible? Only the commander has them and he only has two.
I played for HOURS last night and I never saw "smoke spam". What I did see is that they are fairly large and last fairly long, which is perfect. I also saw inexperienced players tossing smoke when they must have thought it was a grenade. This created smoke in some very unusual areas and typically wasn't very tactically sound. (i.e. I saw OUR commander toss smoke onto an objective we were supposed to defend, that made it pretty difficult)
It's not impossible to defend a smoked area. If you KNOW they are coming into the smoke, toss grenades into to it. It's gotten me tons of kills as the assaulters move into the
safe smoke. It's also time for the automatics, especially the machine gun to spray the area down. It will slow them down.
I dissagree that less than 24 hours after release, people are yelling for changing them already. For god sakes, give the playerbase a chance to experiment. You people are reactionary.
