Small bot farm/level 90 bot question

Hey guys, I have been botting for a while now, and I was wondering on what your guys' take on battlechest botting is. I found that at 750gph it has more ROI than a WoD bot running felblight, but I was wondering if you guys have found a way to generate 1000gph on a level 90 bot 100% afk. I have done tol'vir and achieved that gph, but the profile itself had many bugs, so it is not 100% afk.

Thanks guys!
