Realistic chance that Rito is playing favorites on non-ranked queues

This is a pretty insane idea, but I think it might actually be happening. Quite simply: I believe that Riot slightly advantages one team over the other at the start of every non-ranked game [effectively raising or lowering game mechanics to advantage one side].

Stick with me here for a second.

I was playing Ekko mid last game, and attempted to counter a jungle gank with a well-timed W AOE stun. As the stun came down, both Lee sin and Yasuo were clearly in the AOE, and both has the little "stunned" animation over their head. Yet Yasuo was able to cast and complete his ult (beginning the spell after being stunned), resulting in my unjust death.

That same game, 3 of my auto attacks did zero damage. Sure, you could say I "canceled" my autos, but that would be literally impossible given the fact that I was not inputting any commands on either my keyboard or my mouse. After the first instance I decided to simple click on the enemy champion and watch to see which autos hit (and which did not).

Yes these are small little things, not game-ending sudden bugs that every player will notice. But they can be significant (and annoying as hell in a close matchup). I think something fishy is going on, will investigate further.

Note: please don't comment with something dumb like "bro lee sin shield!" or "maybe he popped a potion!". Obviously I looked at every item every champion in the game had, checked out the death recap, calculated dmg done manually on my calculator, and registered whether or not yasuo's passive shield built up.
