Lets just cut out the middle man and make all GRB maps 500x500 meters with no terrain. Only allow the tanks to drive forward from thier spawn point and give everyone AI gunners. This will make the matches as fast and simple as possible and not confuse players with large maps and varying terrain. It will also speed up the grind since each match will be about 2.5 minute’s, allowing players to get in many more matches per play session.
Also remove the respawn system to mirror ARB. That way players will only ever need one trained crew slot and wont have to spend time thinking about lineups. This will also prevent low level players buying (not) top tier premiums, from being hated as “one death leavers”.
And this will also remove CAS from GRB by matter of coincidence making “tank only” players happy.
I see no downside.
