If you think the bone shield nerf is a wash then you did not understand my post. This discussion is not silly and it is NOT a wash. Losing 4 runes every 5 minutes is a loss. Assuming you use those 4 runes for 4 BS for 4k each average, then it is a 53 dps loss. It may be small, but we are here to optimize, no?
4 runes = 4 Blood Strike for 4k each =16000 damage every 5 minutes that you are losing refreshing Bone shield,
16000/300 seconds =53.3333 dps lost.
Obviously I picked 4k as an arbitrary number for Blood Strike damage. On live, with my gear I am getting more like 2-3k. But the point remains. It is a significant DPS loss. We quibble here over 10 dps differences. Even if blood strike hits for 2k, it is a 26 dps loss.
I agree, it is damned annoying too. And losing the blood tap to cast bone shield is annoying as well. It was always there to save your rotation in case you flubbed something. And if you got the rotation right, it was a nice dps gain. This basically makes blood tap useless.
we're not optimizing anything because it is on a 1-minute duration, and this all of course assumes we're static on that target for all 5 minutes, which doesn't really happen these days.
i'm just saying you've made your point, and you are correct that the change is a dps loss in 3.2. i'd prefer to not spend more posts on it beyond recognizing that though; there are just more pressing things to cover.
