*Skins in the new 750 RP tier feature new texture and model work as well as a new splash image; and some skins in this tier will feature new animations. *Examples: Little Knight Amumu, Explorer Ezreal

Hippalus was trying to make it sound appealing despite it actually being pretty much mandatory on skins, I think. Unless they decide to get rid of Splash Images for 520 and lower skins (which would be hilariously bad).
