Something I find out about that could be a problem. The recon kit has this device. I can't remember the name, but it's basically a tactical insertion like the one in CoD. Now, this thing could be a huge factor. Imagine sneaking around to the back of a base and throwing this thing down. Even if you're killed, you'll spawn in the back of the base every time. Talk about free kills. You'll see the enemy's back more than their front. Dog tags galore.
Or... a guy putting one down in the base the defenders just lost. Now, he'll be spawning behind the attackers. If he's got people to spawn on him, there's a whole squad camping you now. Kill all of them, the recon respawns in the base again and they can start it all over.
It could be easily abused and im certain it will be.
On the plus side, Im loving the weapon customizations. A bunch of scopes to choose from once you unlock them. The infrared looks awesome. It looks like you can just use them too. You don't have to sacrifice a useful skill to use the RDS or whatever. I always hated that in BC2.
