This, all of this. Assault is fun but lacks teamwork oriented gadgets. Recon only has spotting left (spawn beacon is gone). Support is a powerhouse that has both ammo, healing, and defibs while missing the fun of C4.
In my opinion, either give back the healing and defibs to Assault, or make a fifth class focused on healing and revert the changes to the Support class. So we would then have Assault, focused on pushing objectives, Support focused on LMG, ammo and C4, Recon focused on spotting and spawn beacon (yes bring it back), Engineer focused on vehicle repair and RPGs, and then a fifth class focused on healing called Medic.
