Durumu 10man normal - tips on handling colourblind phase

Hi,

We have recently killed ji-kun and had some tries on Durumu at the end of the night. Most of the fight seems pretty straightforward however we seem to be missing something during colourblind phase specially at the start.

Big question is: how do you guys handle assignments for each beam? For us it seems like 50/50 chance that we will be missing someone in one beam and have too many people in other. Can you do some pre- assigns even though beam targets are random?

The second question is during second colourblind phase we sometimes get the healing beam during that phase. Is that normal? and if so how you handle that when you are stunned and for instance yellow beam is moving away?

I hope to get some awesome tips out of this, my last thread pretty much got us ji-kun kill so please lay it on me how to handle colourblind phase.

Thanks a lot
