LS members were saying something about the gobs were accepting relic upgrade mats so possibly related to that? Dunno for sure though.
It sounds like the new weapons will be stronger than current REMA but not related in any way. The upgrades to REMA are to keep them competitive after these weapons come out. Apparently we're supposed to use these weapons to do new master trials they're gonna add, lol.
Will watch more of it later, need to sleep!
