It does seem a little odd, but not completely nutty. Maybe they like having a 5* star team? I have one team I kept at 4* for a few seasons.. Basically holding a ton of points to keep their Q the same, assigning up to just below 4* after Cup draw. They could be doing that, desiring to keep the players at that particular Q for as long as possible?

There was a team I was getting into bidding wars with early on, (he was going for a solid 6* team) but he decided to use the Scout list so I don't ever see him now. But he would always be buying the 18 y.o. gems I wanted, it got to the point I just wouldnt bid if I saw him. Thankfully I only got in League with him once, though I saw him in CL a couple times.
