Been having a frustrating time working towards platinum. I started as 2132 and made it up to 2198. Then it just dropped like a lead balloon to 1891. The from this Thursday on, I hit it hard solo and got up to 2305 yesterday, the the bad runs started again and dropped to near the 2000's again. Fortunately a mate joined up with me for a few games just now and managed to win all 4 of them. So I am currently sitting on 2254, but I am not sure if I can handle the matchmaker throwing me into another cluster of really bad matches again.
I may make it to platinum, but the run there is not even enjoyable. It's too RNG based on if you have players who will try to achieve it, or the other 90% who seem to be lingering around the gold level.
