After selecting a champ/item during Carousel, move the avatar to a spot outside the carousel. There is blocking of champ/item by other players who have selected already. Not cool. A more extreme version of this would be to just hard move avatars that have selected champ/item to small areas at the edge designated for each player. This prevents any blocking/distractions.
There is literally no reason to move the avatar starting location around the circle randomly during Carousel. Sure, the yellow circle helps, but it's still dumb and annoying. That is a code implementation detail leaked into the UI. The champs/items can be randomized without moving each players avatar location. The avatar location should always be at the bottom center. For those of you who are developers, you know what I mean.
You can store each players location in the carousel as being the same order each time. Then, just randomize the champs/items in the inner circle. Simple and easier on the players, their champ location is always bottom/middle. I think this is true. I need to sit down and draw it out just to be sure...
