Getting the third teammate, who had his first ranked game in my promo...

So this happened today...

me and my premade friends hit promotion to gold We played three games. Three games in a row we got a dude in our team who hasnt played any ranked games yet We got tilted We lost promotion Even more tilt Realizing we are playing League of Legends Getting back to ranked Repeat

Why did we get matched with dudes that are unranked, when our mmr is clearly above silver standards?

(btw this shit happened on EUW but the boards simply have more range) (anyways the matchmaking is on all servers the same so no flamerino pls)
