When your in promos does it purposly place you with lower ranked or even unranked people more?

Nope. Promos arent any different from other games. Hell most games are promo for someone.

In my experience yes, i typically am matched with people who are unranked or bronze while i normally play with people in gold

Probably yeah, I can just tell even without looking at rank it seems to put you with players that are on a lose streak
