Just bought another CM Gold boost for 2 of my characters today and both runs got done fairly quickly. The 1st run was pilot and had a few hiccups along the way that couldn't really be avoided and took ~2 hours and 30 mins. I played my mage during the 2nd and it went smoothly and was very enjoyable, was over in ~2 hours.
I highly recommend these guys and I'll definitely be buying from them again.
