Wasn't on any of my bikes, was a friends (most all of mine run just straight 10spd or 11spd RD with 10spd drivetrain or straight 11spd.), checked hanger alignment etc, but nothing seemed to solve the issue. Not sure if the actual derailleur was maybe bent by the previous owner and straightened on trail and hence, fvcked. He bought a in good condition used 11spd setup and everything worked flawlessly - think that 10spd RD maybe was fvcked thinking about it, might have to give the 10spd RD on 11spd cassette a go just to see for myself.
