That silver to gold qualifier is PVP hell. Your points will be too low at that point to be able to get matched consistently with golds but too high to not be paired with unranked players in an effort to "balance out" the teams point wise. This late into the season there aren't many silvers anymore to have full silver or higher lobbies so you get stuck with the unranked and bronze. My win rate actually crashed below 50% when I reached that point in my climb, and I even went as low as 45% before getting gold. A true low point for me. Ever since then though I raised my win rate back over 50% and got platinum rank first qualifier.
