This is something I've always wondered about. We see people promoting custom champion and launcher skins on the forums but never anything for the UI. Coming from a host of MMO's myself, I naturally wondered if anyone created add-ons for this genre of game. RiotCaptainLx graciously quenced my curiosity over on the EU boards.
His thread consists of a barrage of questions to which he gives a lot of well thought out answers. It proves to be a very good read and gives a lot of insight into what is becoming one of my new favorite REDS.
"...UI wise there is a good reason as it jeopardizes the competitiveness of the game. WOW for instance is not competitive and so they can do that (we would love to, but have to think of fairness first). A better UI (or lesser UI) might give hardcore players a big advantage. Something we have to be vary of."RiotCaptainLx, Senior Character Animator, via the official EU forums.
