It's actually a really bad idea to give assault the deploy beacon, after playing for a bit I see no reason to play recon once it loses its ability to create cheeky deploy spots. Sure there will be more gadgets in the full game, but I feel like sneaking around to plant deploy beacons is really good.
The only situation where I'd do this is if weapons get locked. Then snipers won't have access to the deploy beacon. But I mean... if weapons remain unlocked, then people will just play assault to plant deploy beacons for themselves while sniping
