The only reason I bought it was because I needed the third USA BR2 Premium Assault squad at that time, I didn’t care what squad it was.
And honestly, I prefer the original 4+2 version because I can equip engineers with BP weapons.
Rifleman squads are facing quite different situation. If developers decide to to resell their upgraded versions, I would say I don’t like this approach, but compared to directly changing old squads, that will be an acceptable solution.
