So, after the announced talent changes and what-not, most Unholy DKs will now be subspeccing Frost for the 10% increased Shadow damage from Black Ice that they added in.
Subspeccing into Frost means one thing, though. No more Rune Tap. Initially, this may have some of you worried. I have come to let you know that you can rest easy because Unholy healing is going to be great (atleast every 3 minutes it will be.)
How, you ask?
Glyph of Death's Embrace + Glyph of Death Coil + Lichborne
Glyph of DE refunds 20 RP when Death Coil is used to heal.
Glyph of DC reduces your DC cost to 32 down from 40.
Effectively, this means your Death Coils will now cost 12 RP if you use them to heal.
Most Unholy DKs will pick up Improved Icy Touch and Runic Power Mastery out of Tier 1 Frost to get to Black Ice. Runic Power Mastery ups your maximum RP to 130.
Let's do some math. Remember, your Death Coil costs 12 RP if you use it to heal. How many times does 12 go into 130? I'll tell you - 10. That means you can Death Coil heal yourself 10 times after popping Lichborne. If that's not enough, you could always pop Horn of Winter, toss out a few attacks, or pop Empower Rune Weapon for more RP and get in some more heals.
This is going to be some really nice healing in those OH **** moments with the loss of Rune Tap.
