I switched full time to the scout (with SMG) for the last week of the beta (trying to get the augmented camo) and I was able to 10-15 kills each game while maintaining a positive K:D ratio and trying to capture the objectives. So while I would like the scout class to get a little boost, I don't see it as extremely weak and useless like I've seen a lot of people say.
One of my major gripes with the game though is the maps are way too small for a true sniper to be effective. I read on the Ubisoft forums that the Mill was the largest map in the game and if that's true I'll be incredibly disappointed. I remember maps the size of Rocky Cove from GRAW1 where you could snipe from beach to beach and be useful while also having part of your team with ARs closing in on the enemy.
