DS and avoidance
If you avoided enough consecutive hits to lose the shield due to the time expiring, then maybe I could see that arguement. I don't see that happening because there's not enough avoidance, even stacking the heck put of it, to make that happen. You would also have to not be refreshing the blood shield with a new DS.
I'm not a theory crafter, but I can't see the value of their arguement.
"he doens't need healing, he doesn't need healing, he doesn't nee-WHAOSHIT!wtf was that man!". Please stop leaning on TDR. -Teng
