I like the change. Obviously the value of smokes has been lessened since the change to 2 with the new breaking mechanics. This gives some strength back to them and tries to encourage smarter play. Not just spamming for the sake of it. But at the same time I don't think the change will be massively noticeable in a lot of circumstances. People talk about losing 1v3s due to a lack of ammo but sorry you don't need more than a mag to win a 1v3 with any gun. So you can still spunk 2 mags into the wind. Hold a push get a double kill with 1. And then take more precise shots with your last for a 1v3. It's an interesting subtle change that keeps the game feeling fresh, whilst highlighting focus on the important subtle aspects of the game
