Riot, please prioritize updating existing RGM games for the new client over making new modes
Hexakill (twisted treeline), URf, and One for All are my personal favorites and I'm guessing they are for a lot of other people too. I wish Riot would just get these up and running before working on new stuff. I get it that people want to see new game modes come out but I personally have seen way more requests for the old favorites (especially URF).
I think there would be a lot less complaining about Poro King and Ascension if all modes were actually represented in the RGM more evenly. Hopefully Riot will take notice of what we've been asking for and get theses modes out to us SOON!
