i actually don't know how much more we'll be changing, nor do i know who makes those calls. we definitely want to preserve a certain qualities and styles in our aesthetic, so i'm sure there's quite a bit of professional discussion surrounding the process.
personal preference: there are some champions that i'd be fine going 100% tencent art (akali) while others i'd really want to pick and choose (miss fortune). i'm interested to see if any other champions/skins will received updates anytime in the near future.
Ive been inclined to believe that they don't change what you do. O_o ?
