Dev, and Gaijin, want money.
1 way is : encourage players to buy slots.
So:
Imo, If Dev want players to buy slots, they need to give players new vehicules, no skins for actuals vehicules.
I don’t like these skins. They are not cool enough and have no practical function either. This is just a lazy act. Why aren’t there more unique new vehicles?
Probably a mix of reducing cycling (although it does not present cycling with old vehicles) and the reasons @Adamnpee stated.
I dont know what that will do since vehicles dont mean new squads, just more vehicles for current squads. If DF wants more slot buyers, they need to offer more squads.
You are right, I was thinking more of the concept of e.g. spamming Jumbos with the old Jumbo squad and the new GO Jumbo in the other squad, but I am not sure if we got a new TT Jumbo as well.
Well, my point is that if you already had legacy squad that could use certain vehicle - you are already most likely have multiple copies of such vehicles.
Funny thing is that those camos can be used on those old vehicles. Effectively giving veterans BP vehicles to legacy squad, not just new ones.
