You will need: 5x spirit beast
A selfheal macro:
/Cast Spirit Mend
And a Stampede.
In other words, if you have 5 spirit beasts with you , you have lay on hands on 5 min cd.
Cast Stampede--) Use macro --) At full HP in a sec + geting healed over time
When you activate the macro all 5 spirit beasts will heal you. (i suggest you dont have spirit mend on autocast because you pet can use it)
