Smoke grenades should not be exclusive to support

The move to make smoke grenades exclusive to support rather than being available to other classes or aligned to recon in practice does not work as they are so rarely used. I understand the thinking behind it but in reality players don't play that way.

 Most support players are incredibly aggressive going for kills or using gadgets for their own benefit, they never use smoke grenades to help them revive other players or help the team move even when that is exactly why they have them. They're all using offensive grenades and not smoke making it entirely redundant sitting in that class. Just getting some of them to revive players consistently is hard enough, having them use smoke to create concealment to revive in the open is nice in concept but they don't do it. 

Either they need to remove the exclusivity for smoke or smoke should definitely be moved to recon who historically were the class who used it the most in previous battlefield games. Either to help their team reposition or to allow them to close the distance on vehicles to use c4. Another grenade could replace the exclusive one for support. The motion grenade is nice but has far less utility when recon already have plenty of ways to spot. 

The reality is that it's just largely unused exclusive to support and so many situations in the game could benefit from a team using it more.
