It's unlikely that Sersi will get a feeder anytime soon. We've got something like 14 five-stars that don't have feeders yet. It's a ridiculous situation that the devs could easily resolve if they weren't so dead set against retroactive rewards. They need to get over that and catch us up to current releases. They can then have new four stars feed new five-stars. I don't expect this to ever be resolved.
Sure, but what then would I move my 5* favorite over to? At this point the goal is still to champ all the 5*s, and he is the only unfed classic on my plate right now until Big Wheel drops out. I’m probably going to leave it unless I get some sort of epiphany on something else to do with it.
