It's still possible to level up Scoped-In and Cloaked in Plunder and TO. ND removed Oh, Snap!, but not Assassin. You can still get Long Rangers in those modes, too.
Still... Leveling up boosters in Objective modes is like using a cheat code, you're not even putting effort into getting them to Gold, just mindlessly killing people who are trying to play the game properly.
Yeah, you're right about that. The funny thing is when I was upgrading WE in Plunder I still played the objective. It's nearly impossible for me to ignore objectives, especially since Plunder is one of my favourite modes.
