I think pretty much everyone would agree with you on this. Recon was nerfed so heavily in BF3 that they were only effective at range which lead to the camping behavior we're all used to now.Sounds like they're basically back to what they were in BFBC2, which, to my way of thinking, was a fantastic design for the class. They were too "passive spotter + sniper" in BF3. In BFBC2 you could play aggressive recon, move with your team, keep tossing motion trackers ahead, slap C4 on vehicles and walls and stuff, etc. On the whole, once they finally ironed out all the wrinkles in balance, I thought BFBC2 was pretty much the best balanced multiplayer FPS I've played, so it's nice to hear they'er working the classes back in that direction.
Of course it's only helped somewhat, much of the camping behavior is still very much alive in BF4, at least in the BETA so far.
