I would like to get a backpack slot on my engineer and AT-gunner, despite I unlocked the secondary weapon slot for the soldiers who can bring a secondary weapon. Soldier from some classes will only suffer if you make this selection (see pictures).
This problem applies to all event and some premium squads.
I guess it’s a coding issue since it works wonders on old premium who recently got an assigned engineer and they’re not part of the premium squad originally.
I didn’t even consider changing slot, because since those guy’s weapon is both unique and, I dare say, quite effective, I’m fine with them carrying either extra ammo or spare medikits for extra survivability.
I think that your issue comes from the fact that this squad’s engineer is coded as a special unit same as his fellas (hence he can carry the same special gun), while engineers on older squads are regular guys assigned to an optional slot, so technically not the same class as the rest of the squad.
Frankly, I don’t see a reason to pick a second weapon slot rather than a backpack slot.
The only ones who might have some kind of benefit to this are assaulters, where you could choose the 2nd weapon as a bolt action or semi-auto rifle for longer range fights. But I am not sure if you even can pick anything other than the SMG/starter BA in the first place, which kind of makes this selection even more pointless.
Heck, it’s similar to the issue I’ve posted some time ago:
Yeah, I suppose it can make sense for machinegunners.
But I still chose a backpack for them, at least this lack of longer range capability can be somewhat compensated by more ammo with ammo pouches.
BRRRT go BRRRR.
Heh.
