People shouldn't be getting in position before markers, if they are. Sounds like that might be the issue. Otherwise it's just a means of compensating. If two people are on one side and they both stay on that side, it's going to cause issues, and a flat out wipe in the final phase. You need to set up a prioritization order for who goes where, and if two are on one side, know which of the two goes opposite.
So, you have OT, NIN, and BLM on the left. Let's say OT and NIN get targeted. OT would stay on the left, and the NIN would quickly run across to the right and drop his on that side.
Again, another scenario. This time the OT and BLM. The OT would stay where he is, and since the BLM is already behind the boss, they have more than enough time to run to the right and drop over there. It just boils down to communication and raid awareness. If you compensate instead of anticipate, it trivializes things. Have certain people with set locations. It's easier to make the melee and OT these people, as the ranged won't be right up on the boss anyways.
The only exception to that rule is whichever side has the OT, as the OT will stay put on the melee on that side will split off to the other.
I threw together a quick diagram to explain. This is how you setup should always look when preparing for earthshakers.
0 = Boss
1 = Monk
2 = Ninja
3= OT
4= BLM
5= BRD
Those are the only people who will ever get markers. I'll break things down a bit further.
1 = Stays right always.
2 = Stays left always UNLESS the OT gets earthshaker. Then they go left.
3 = Stays left always.
4 = Goes left or right
5 = Goes left or right
So, for example A. The Monk and Ninja got earthshakers, so they go to their respective sides.
In example B, the Ninja and OT got earthshakers. Because the OT is designated to always stay left, the Ninja goes right.
In example C, both respective sides are open for their jobs, so they go to their spots.
But in example D, both the Ninja and BLM are on the same side. Since the Ninja is always designated to go left unless the OT has it, the BLM goes right.
Example E is the same, only reverse with the BRD going left because the Monk is always going to stay right.
But bottom line, OT, NIN, and MNK all have designated spots. NIN and OT are the only exception. BRD and BLM will always have to compensate and run to the proper side based on whether or not one of the designated spots is taken.
Hopefully that helps clear things up, but feel free to ask more questions if need be. :>
