Once I had two 8v3 fails in a row, so you are not the unluckiest here. One game later I got a 8v2 draw. I'm still wondering how to roll just an 11 with 8 dices, but it seems to bee possible.
I lost 8v1 once (not in 1v1q) back when there used to be a bug letting you roll 0 in attrition (yep, back when I played attrition...). Luckily, since it was attrition, my opponent was still reduced to a 1.
