Champion Mastery & Twisted Treeline... Rito plz.

So I'm a little confused... how have we already started adding the next level of Champion Mastery (6 & 7) but yet STILL have no option to get Mastery 1-5 on one of the other main mode of League Of Legends. Somehow, Riot has enabled champion mastery for the "Here for a Day, Gone tomorrow" modes such as Ascension, All for One, and EVEN the obnoxiousness that is URF.... but Twisted Treeline... the mode with an entire ranked queue centered around it. Nothing.

What gives Riot? I always took it as a "Hey, we're working on enabling it after the initial release on SR." But now, to have added the next phase of Champion Mastery on SR, as well as it being enabled on EVERY rotating game mode. I'm left feeling a little left out, seeing as Twisted Treeline is my main and preferred map to play League on. Feels bad man :(

rito plz! what's up???
