Can I say that I really love the "D&D" themed skins
I mean they're fairly cheap, still well made, but above all are just a nice nod to D&D or any other table top RPG game out there. I can't say I have all of them, at the very least I only have Gragas', but looking at the rest they're just so neat and cool. Sejuani riding a giant lion, Karthus is now a human, Bard is actually a bard, Ryze looks like the Gandalf wizard we always imagine in these games, etc.
The only thing I wish of these skins is that we try to see more in the future but also more skins that focus on the villains/monsters. If I recall the Singed, Kayle, and Nocturne skins were also suppose to hint at this series but as like the dungeon bosses if I remember. While this is nice I'd also like to see more boss skins with more variety as well, like Orc Warchief Sion or Beholder Vel'Koz (kinda obvious).
