I caved into a friend's requests and re-subbed for a month to see. I do not have WoD but might on christmas. Anyway, I find that once I go through a rotation, using either Runic Corruption or Blood Tap (doesn't matter which), I still sit there and just auto-attack maybe 20% of the time. I have no tried Runic Empowerment.
This is confusing. I remember in Cata, I had so much Runic Power coming that I was spamming Rune Strike often enough to warrant using Unholy Presence in PVP, questing, and some solo raid runs, as many people figured out. This led into the 1 second GCD from Unholy Presence being given to Blood, too, (and I think Frost? I didn't play Frost that much in MoP).
Then, came MoP and I was worried about Runic Empowerment no longer being baseline and Blood Tap being changed to a crappy Charges mechanic. I picked Runic Corruption and wound up having less issues than I was afraid I'd have. This was because they gave improved Blood Presence better Rune Regen partway through beta. I was a part of the MoP beta and until the better rune regen came in, Blood was as crap as I am experiencing right now. Only when Runic Corruption was being an RNG bitch would I have dry spots, but Empower Rune Weapon was usually off cooldown by then, so no problems!
So why was Improved Blood Presence gutted without giving me some way to still have decent rune regen? I've ran 3 instances and so far, almost died twice due to not being able to stack Death Strikes as on demand as I remember.
(Side note, the removal of Heart Strike is throwing me off incredibly so. Hitting Blood Boil to get a group of mob's attention, since DPS like running in before I get to spread DoTs, then using Outbreak or Plague Strike and Icy Touch, THEN Blood Boil again... so weird to me. Moving Blood Boil to where Heart Strike was is helping, slowly.)
Do I need to be stacking the HELL out of Haste and Mastery, rather than Crit/Parry and Mastery with some Dodge, as my MoP and Cata end game days remember?? Or did Blizzard decide it's okay for Blood to suck incredibly amounts of ass before getting Runic Strikes at 90, which might help at least spam Death Coils more often?
Do other tanks need to stack Haste? I can see maybe Guardian Druids and Monks doing it.
