So many reasons:

- Gated behind Moogle Ex.
- Independent responsibility that affects the whole group. Someone screws up? Its probably a wipe.
- Some degree of Randomness. Specially lethal to unprepared players.
- Pretty much requires some sort of external Voice software. Communication is everything on this fight, and chat doesn't cut it.
- Melee unfriendly.
- Ridiculous DPS check. My static has half the team on HA weapons and it's still cutting it close. I have no idea who designed this but I'm pretty sure its impossible to do on the base iLvl required.
- Best winning strategy not widespread, requires good DPS healers and a DPS oriented tank.


Seriously tho, that last point is the make-or-break point of most Ramuh fights. If your healers and the tanks are not DPSing the adds your chance of clearing becomes nearly zil. Too often I see the current MT stick on Ramuh instead of attacking an add behind them, or a healer complaining why the DPS slacking when all they did was cure. Healers that can actually DPS amongst all that chaos are few and far inbetween :/
