I'll upvote anything that asks for URF, OFA, or Hexakill. The problem is that it's never gonna happen. Riot hates 'the big 3'. They impact queue times for ranked, and Riot only wants us playing LC$ Simulator. They feed us a steady dose of bad RGMs to hurry us back into playing LC$ Sim.
Then we are insulted with silly excuses about how it's harder to get popular RGMs to the new client, or that 'playing it less makes you enjoy it more'(while promoting ranked SR, a game that is built on playing a single 5v5 map for 8 years lol). They throw this torch of garbage out in hopes that the white knights, apes, and 'dude I work with new clients, and I can tell you....' guys will run with it.
League was created from DoTA, which was a custom game in WC3. If Blizzard would have limited custom games to RGMs and only allowed us to play DoTA once a year, LoL or mobas would never have been born. It's bullshit that a game created from custom games locks it's custom games in a vault.
I enjoy URF, OFA, and Hexakill so much that I'd pay a sub to have them permanent. The only reason that I don't spend money here anymore is because we as customers aren't given the option to play them, and lied to about why.
