Hey I feel ya. I 99% of the time queue solo. Ive hit my glory rank one in competitive (not fun solo) and im about to reset my valour rank for the second time. It can be done. I am not a good pvp player. I manage a 1.5 KDA bit I hang in there. I wanted the exotic ghost and the crucible chest piece. I almost have them both. At the end of it, Im a little bit better for it. It was/is a grind but for me its worth it. If you feel the rewards you are chasing are worth it too then grind on!!
