Xerath, Vel'Koz and Kassadin are so forgotten, they didn't even make it to Mobile League.
As seen in the preview and champion list.

But by all means, we gotta have that Yasuo in there.
Riot, i know you're confident that Mobile League will be a hit, because you know your army of brainwashed addicts will consume any and every piece of content you produce, but if you don't want the game to get boring after 1 week, i suggest you expand the roster.
Also, saying this now, making us buy the skins we already own for desktop seperately for mobile, and pricing them at their desktop prices would be immoral.
