I love the Battle Academy Skin's Idea.
I know your starting out safe by giving champions you know will sell skins these skins, such as Ezreal and Lux, whom i think everyone can agree on were pretty tired of getting skins.
None the less i like the aesthetics and i'm happy that Jayce, Graves and Katarina got skins with this skin line as well, but hope if this skin line continues you guy's are more adventurous with the champions you chose to give them too and that a different champion who doesn't have an 1850 skin yet get's one.
Side Note: You guys said something about bringing Project back this year, i love that skin line but 3 Heavily Auto Attack focused champions got the 1850 skin for the skin line on all three releases. Nothing specifically against Vayne, Yi or Ashe but it's nice to see other champions get the spot light and there are a lot of champions that never get it. Not to mention that there are lot of new champions and it seems that they tend not get skins often, it would be nice to see more love for the newest champions in the game as well.
