Markers

The B and C markers were used for Earthshakers as they are proximity damage in Sephirot EX.

Earthshakers have been changed in the Unreal version of the fight, and are not proximity damage.

A: Party stack at the start of the triple-knockback sequence.
B: DPS Earthshaker (not really needed for Unreal)
C: Healer Earthshaker (not really needed for Unreal)
1: Green players stack (with tethers).
2: Orange players stack.
