Oh yeah, you're a much better player than I am and playing at a much higher level than I am (obviously). Things in the 3.5/7.0 mixed world seem to be quite different from what you're describing (based on my own experience, anyway).
Well, then you and @Cindysphinx have common ground since she's a 3.5 [former 4.0] and has plenty of MXDs experience. She doesn't appear to have the same attitude as your partners, though. Maybe you two ought to join forces.
Regardless of level, though, I've had partners in local park matches blame me for the loss even though I was clearly the better player and doing the lion's share of the work. Maybe I was only doing 75% instead of 90%. I just nod my head and note that flaw in judgment for when I'm on the other side of the net.
