It feels more satisfying
I just finished promos to gold on a second account I have (trexhaslonglegs) and did silver II or III all the way to gold V w/out duo que on this one to see if I could get it on my own or got carried by some friends on the first account. Feels satisfying to hit gold w/out a duo, but it was definitely more stressful some games. Now to try and get good enough to hit plat maybe.
