Week's Champ All Mid

Seriously, this is hardly even random, every week you are getting 2 champs constantly. It's Riven and Yorick for me this week, good, these are the best champions for that mode.

Yorick is fine, even if you're a baboon (go like every single champ in the game in ARAM : Dark harvest + Triumph), on the other hand, Riven can be good if well played

Buuuuuuut it's not the topic, I agree on this one, last week I kept seeing Caitlyn and Ziggs every single game, it's truly not random

And my personal play agrees with the OP. Especially when I get Skarner 3 times in a row. The odds of that are so low as to have 4 zeros before the first number if you assume true RNG. .000036%.

I sort of suspect I know why this happens though. Instead of fully pulling from a random pool of valid champions for the individual player, it adds up the TOTAL pool of all 10 players, and then dishes out the champions, preventing duplicates and ensuring a valid selection. So on a Skarner free week, there are 10 chances of Skarner, while there may only be like 1-2 chances of a lesser owned champ like Twitch.

Lets pretend all 10 people can play 30 champs for the purpose of this specific ARAM. There are a total of 300 champs on the board, of which the free week champions are 100 of them. Now because it can't allow duplicates, the pool rapidly diminishes as the duplicate champions are picked out of the pool, but they still held a very disproportionate percentage of the champion pool chances for each individual player way higher than it actually should have been. It should have been a 1/30 chance of getting that champ, but instead it is more like a 10/120 chance. This chance grows even further as other players are assigned the random free week champs or other duplicate champions, such as the likely cheap ones or ARAM Smurf prefered pool.

This all player champ pool preferred weighting would explain why such similar team comps are far more likely, ESPECIALLY when rerolls are also taken into account to knock out some of the lesser desired picks.
