Interesting, I have been going back and forth with Pivot on the same issue and all they are willing to do is give me a bro deal on another Pivot bike...
I have had mine for a little while now and agree about the suspension, but have also experienced the same with out-of-the-box Fox 36 in the past...the emtb 'tune' is likely geared towards heavier riders, so I'm at 15-20 psi below the recommended for my weight and it made it a little...
