Profile Layout Concept
They just released a new profile layout today and it is not the best in my opinion. Right now there is too much space below the banner not being used and unnecessary things being shown like the clash related items and honor level on other people's profiles. In my opinion the clash banners you have unlocked should replace the green banner behind your name. You can still change between the default and ones you have. The boosts, rerolls, and chests should get moved so you have more space there. They should also start showing your 3 most mastered champions again with the mastery points for each above.
Here is a sloppy concept art I made on how I think it should look.
