"Outside of the player population, Twisted Treeline’s art, map design, and even game pacing don’t meet today’s current quality bar and player needs."
This just infuriates me. They've left this mode to rot for literal years, refusing to properly apply any sort of balance changes for it. Then, instead of investing time and energy into updating it, they just let it die. I am actually done with Riot only investing resources into things that make them money.
They even admitted URF is their most popular spin off mode "though TFT is giving it a run for its money" and yet, because they haven't found a way to properly monetise it, they won't make it a permanent game mode.
I am absolutely furious about Nexus Blitz though. It was unquestionably the most fun I've ever had playing League. It was the PERFECT mode to calm down in between ranked games, or to just have some good fun. ARAM is okay, but the psuedo random element that can leave you playing as a completely useless champion, such as Udyr, for up to 40 minutes doesn't match the guarenteed 20 minutes of a champion you actually enjoy, with tasks that you don't find in any other game mode, but because the only money making idea they had for this game mode was the world's most useless passes, that required you to play 10 games + a day to get full value out of, they too are not making this game mode permanent. It just makes me so sad that Riot is clearly only in it at this point for the $$$ instead of making a fun and enjoyable game mode for the fans.
But then again I guess you can't spell 'League' without 'EA'.
