Looking for duo partner

I am currently looking for a duo partner that is ready to get to gold, regardless of if we lose games or win them all. I am looking for someone mature, pref 18+ due to past experiences with raging. If you are already gold that is even better, because most of the people I play with are gold and when I solo que I get less lp. If I duo in a rank higher than mine I get better lp, and play just as well. Please add me asap Thanks!
