I feel you're pain, at least it ranked you high than my SR with more wins. Started the QP on Saturday & finished it yesterday. Won 5, lost 5. Got gold's in most games, on point for most of the games & finished 1070 lol. Previous season was 1590 ! Now, I don't know if it's because I paired with my mate (who is 500sr player) ?
I'd like to get up to 2000+ SR but I think my mate is holding me back (I could be wrong & it's just me as a below average player) but I feel my FPS skills that bad, BF4 I rocked even though it's a different beast ! Last season was rollercoaster of SR highs & lows falling down to my placement it gave me. One plus to trying to get a higher rank above 2000+ would be I couldn't pair with my mate haha.
I know this as a complaint of many players but I do seemed to be placed with idiot's who contributed very little to capturing a point & find myself trying harder to fill the player loss.
The good thing for me is being old (41) & not having a high in SR doesn't eat me up (though I always look to be better), couldn't care less as long as it's fun & I do me bit.
