I like most of what you lay down.
Definitely a yes for the assault, their class should have an aggressive response for most of whats to come. Since assault has 2 slots for primary weapons, their second choice should vary between shotgun, RPG, so on..... keep its current gadget selection
I'm on the fence about making assault rifles the primary for medics but I think i would rather see them have the spawn beacon. Since they are are trying to keep everyone alive, they should be the ones to set beacons on safe areas ( medic tent)
Love the engineer, that way they can focus more on suppressing rather then vehicle hunting. Even more so if they bring the mortars backs, keep the mines so they have a passive way to hinder enemies. They'll fortify positions
Now for recon, my favorite class I agree, recon doesn't really need much changes, I don't mid losing the beacon since it seems they are going to make them more stealthy. That being the case it would allow players to either sit back or scout ahead. Insta kill would solve the issue with kill cam and its current gadgets would allow recon to scout ahead and assassinate, flank, flush, or even sabotage (c4) the enemy.
Let me know what you think of the changes I made. Great idea about reworking the classes roles
