ARAM is a joke right now
Sona is posting a 68.5% winrate right now. Ziggs a 67%. I just fought both on the same team, which also encompassed Lux, Varus, and Ahri. Keep in mind, Sona's winrate was NO HIGHER when she was DISABLED in URF. It's disgusting. There is NO winning against comps like that, and that is inherently unfair when a "random" distribution, as advertised, would keep comps like that from forming in the first place.
And you know what? I would be fine with that kind of crazy composition if it was rare-- a statistical outlier. But it's not. Over half of my ARAM experience is one troll team vs. one team of solid, S-tier rolls. How? How does this happen? How are these champions posting such incredible win and pick rates? It's supposed to be fucking random.
Just open up the entire champ pool for FUCK'S sake. It would solve fully half of ARAM's problems. I'm tired of your inaction on what otherwise is a fun mode. HA is the next Crystal Scar because of Riot's disgusting and outdated policy on alternate maps. It's fucking embarrassing.

and rr'd her. The enemy team ended up getting her when they rr'd. So seems sorta random to me.
