We do MT picks up red, OT green, BRD on blue, we burn the blue before it switches, green then red.

For 2nd meteors we have an odd way, but its worked for us ^_^, split into healers, ranged and melee. each go to one of the small circles (where you place the 4 golem meteors, then place em between the fingers and on the fingers.

Wierd way but has worked for us for 20ish kills pre 2.4 and multiple after.
