It really depends on the Champion. Our goal with reworks is not the change the champion simply for the sake of change. Some champions have deeper kit issues so bigger things need to be changed, and that means the other abilities likely need to be changed as well to be in harmony with the bigger changes. Recent Champions we have done VGUs on haven't had as big core issues in the kit, so we haven't had to change as much. Like whenever we get around to Skarner that will probably have to be as big as some older champs like Galio, Sion, Urgot, Etc.
