Vampiric Blood - OP?

Well, I must say that I am very disappointed in the upcoming DK tank changes not because bone shield is going to be bad, but because Vampiric Blood is going to be overpowered. I am super excited to move into tanking blood, but I wish this wasn't why.

Why am I upset with a move being overpowered? Because its going to get nerfed shortly after for the same reason Bone Shield and IBF were nerfed, PvP.

Vampiric Blood is going to give 50% Bonus Healing AND 20% bonus health for 20 seconds (30 SECONDS GLYPHED!!!) People say if its to good to be true it probably is, and this is what we are being given, something way to good to be true.

So blues say "We want moves like IBF to be more like shield wall" yet now you give us even more reason to NOT use the moves like that. Why? Because we can have a move up for Half of a minute. 30 seconds is a long time, and when timed properly only gives 15 seconds of wait time where you don't have either this or IBF up and running. So do you die in those 15 seconds? Not if you have trinkets such as monarch crab or other 1 to 2 minute cooldown trinkets. Your good to go, and you have an OP tank.

This is imbalanced in both PvE and PvP. I'm addressing this now because if this goes live, people will QQ, and it will get nerfed. I'd rather skip that whole episode, and either change the 10 second extra duration glyph or make Vampiric Blood a little less attractive... maybe 15% bonus health. I'm not very good at balancing numbers, but I do see when things are going to be imbalanced, and this is something that will cause problems.

QUICK AND EASY VERSION: Vampiric Blood will be the new bone shield, Nerf it now or Don't Nerf it EVER!
