There is nothing wrong with ignoring them altogether either. the value of them changes on your raid, its size, its dps, and your healers. Like Cookie said, RE is never a great option unless you are simply trying to rank and are going for the most throughput. RC is a fine option, though i'd recommend going to BT for Blade Lord and Sha of Fear.
How to use BT on those fights:
with BT you are going to sit on resources a bit until you need them. Get at least 10 charges of blood tap before Overwhelming assault (balde lord) or thrash (sha) and then dump all your FU runes for 1-2 death strikes then use BTx2 to get an extra DS. Theres more room to optimize on sha, but it won't matter for normal mode. Just make sure there is at least 1-2 death strikes before each thrash.
BT is off the gcd, so you can make a macro like this:
/cast Blood Tap
/cast Blood Tap
which will do BTx2 on one button push
