So with my 5x death knights my only focus is really pvp. I'm just wondering what proffessions would help increase their survival rate the best as that's their weakest point going a Frost / blood spec.

I plan on making all of five of them herbalist for the lifebloom spell, with hopes it gets bumped up in the future.

I was going to make all five alchemist for the increased affect of guardian / battle elixers, but am wondering if their is anything better I could do.

So far this group will have:
Bandages,
Potions,
Lifebloom,
Improved rune tap
Blood Presence (Not improved)

3 Fear removals (human racial, trinket, lichborn)

Any thoughts? Thanks
