Ok so with the extra reserve upgrade being useless, why don’t it become a new feature called “reserves” (yeah I know it’s exactly the same). So essentially reserves could be a new feature that allows dead teammates to (kinda) respawn, essentially a new squad member spawns in from reserves and rejoins replacing former dead teammate. It can be balanced however with timer/points/kills etc. before allowing reserves to come in and how many at a time. Of course the upgrade can be correlated with this however needed such as % or +.
I think this would be neat because I hate being 1 man left and respawning so I can get more men if in that situation or simply you’re doing good playing the objective and need more men but don’t want to respawn.
