Since we could farm upgrade runes in campaign mode and in the future BNW... Right now I think someone sugested double the drops in the update discussion thread. IMO that was enough to "fix" the problem untill BNW comes, since it will be the place to farm upgrade/evolve runes akin to LoL for upgrade/evolve shards.

I know and I think the devs should find ways to get money to continue support and update the game, but making the game a pvw is in the wrong direction. I myself am playing since launch and still don't have 100 talismans 5* or maxed, feel really bad to see someone begining with tons of maxed 5* talismans by paying when pvp comes out...
