The current grid method is wrong

I’m level 140 and I’m having fun playing, but there’s one problem. Only minis you don’t currently own will appear in the grid. Of course, I think it’s good to have all the minis because you can increase the level of your collection, but I don’t think that’s important. There are also minis that I don’t want to own. I think it infringes on the freedom of owning your own collection.
