When are they going to fix the rp on the pbe server

I'm starting to think never because they turned around and made all champions 1 BE on the PBE. Based on their actions I think they're changing it to be just BE, but that's just a theory. They could still fix it eventually, but I don't know.

They made a post about this a little while ago on the PBE boards.

It's going to take 'a while,' so there's no real ETA for when players can get RP on the PBE again. However, they have discontinued granting RP through player support (in other words, they won't be granting RP to players writing in tickets).
