I'm gonna try and start switching in Barrage on Wind Lord. When we killed him last week I used GT, I want to see how Barrage does.
I imagine the ideal conditions for Barrage will be:
1) Full SrS on every target.
2) ES on CD/ExpT on CD
3) LnL on ICD
4) ToTH not procced.
5) Between 30 (min for Barrage) and 40 (min for non-ToTH MS) focus.
and of course all major CDs on CD.
