1/5 TE's you wont get procs
2/5 TE's you wont get procs
3/5 TE's you will get blue but they can take a while
4/5 TE's you will get yellow but they can take a while
5/5 TE's you will get red and the proc rate shoots up.

At 3/5 testing as blm + nin/war, it has taken 10+ vokes to finally proc.

My testing last night shows that the specific KI's dont have any effect, its just the number of kis that does. We killed them in a completly different order and still have the none > none > blue rare > yellow rare> red common pattern.
