So is this really how the Promo series system works?

Before I get into promos every game I play is such a nice match even if I lose, but every goddamn time I get in my promos that's where I start to feel that I'm bound to lose to matches I'm about to play. I'm not even gonna say on in here anymore because of how many times this has happened and how bullshit it is, I mean what kind of stupid crap comes up with that shit to put you with a bunch of ragers and trolls when you are about to get promoted? Really Riot?

I'm sorry but fuck you to the guy that came up with this bullcrap.
