Ye

It would be interesting if returning weapons from original R2D would be unlocked through prestige

No, it shouln't, it will just increase the grindy aspect of R2DA and Pr does not want that. btw, i got ideas on weapons prestige users should unlock by prestiging

^ theres a reason why pr dont add survival and campaign in a single map

Maybe add some benefits in weapons to prestige players like giving golden skins a use but you're kind of pushing it with chinalake being a prestige only weapon
