It would be nice if there was an in-game service to convert a champion into a chicken of the same rank, for a nominal silver fee of course.  Maybe by roasting them on the campfire idk. 

Another beneficial QoL improvement would be the addition of item rank to filter, and the ability to sort items by stat/substat, with a toggle to remove the set groupings (one large pool of items, sorted by filtered criteria)

The ability to click on a player's portrait to view their information, and then click an ignore button to suppress their chat messages on the client side
