Currently, in Lone Fighters, if you get killed when using a soldier from a specific squad, you have to die with another soldier in the other squads in order to spawn another guy from that same squad. This makes it quite underwhelming when you are looking to level a specific squad in this game mode, since sometimes you get unlucky and are the first one to eat a bullet in the charge. Then you have to wait a lot of time until your next soldier from this squad is available.
My suggestion is: allow us to spawn soldiers from the same squad freely. If that specific soldier dies, he’s gone permanently and can’t be spawned again. But you can still spawn the others on the same squad right after, instead of having to murder two guys from the other squads in order to get back to the one you want to play. This “squad cooldown” works in Squads, because you are already spawning the whole bunch and have the whole squad at your disposal at one time. It makes sense for them all to have a cooldown before you can spawn them again. But not in Lone Fighters. This allows people the freedom to play whichever squads or soldiers they want at any given time, provided they haven’t been killed ofc.
