Glory of the Hero - Red Proto Completed

[Bollwerk]

To get Less-Rabi, here is what I did:

1) I respec'd all 3 shamen with 5/5 reverb
2) I created /castsequence macros as follows (these were my main dps spam for this fight):
.....a) /castsequence Wind Shear, Lightning Bolt, Lightning Bolt
.....b) /castsequence LB, WS, LB
.....c) /castsequence LB, LB, WS
3) at 50%, I used counterspell with my mage (I had my mage dps button as a different button, so I could stop dps with my mage as 50% approached)

It still took a few tries, since he will sometimes transform at 1% or so, but I eventually got it after a few days.

I now have 4 achievements left for Glory of the Hero. Looks like Split Personality and Make it Count are going to be the hardest.
