RS700 Horrible Bufferbloat...

Hi all, 

Was wondering if maybe there is a way to fix the bufferbloat caused by this router while gaming? The QOS is awful, tried that, limited download even and upload.. still got a F on Waveform bufferbloat test. I realize I really screwed up buying this as a competitive gamer, and realize now this is not remotely a gaming router. For some reason it showed up on Amazon search as a gaming router. Ive already disabled armor, turned off flow, but I think I am in between a rock and a hard place. I can not find any alternative firmware with real sqm, or any firmware for that matter. Was curious if there is a way to get beta updated firmware? I am not sure what to do, I hate to eat a $600 dollar waste, but its looking like that is my only alternative. I knew I should have bought an  ASUS. I am a dummy.
