I personally dislike only being able to choose between 2 randomly selected champions when I hit a fame milestone.  Currently I end up savescumming to try and get an appealing champion, but that is far from a desirable method.

What I would like to see is a mod that either presents a greater number of champions for selection every time I hit a fame milestone (so instead of 2, we might see 4-8, whatever fits the screen), or else a mod that adds a button to reroll the selection, such that I can keep hitting that button and seeing a new set of two champions until I find one I like.
