Estimated DPS in darklight

[Bardo]

You also need to remember that ADS gets 20%+ defensive buffs against certain types of damage depending on which nodes you kill to get to him.

So if you go down the west side, your bards, dragoons, and monks WILL be doing less damage at no fault of their own.
If you go down the east side, it will be paladin, warrior, black mage, and summoner that take a hit to their damage.

You don't really need incredible dps to beat turn2.
If you handle the Rot and don't stand in Laser/Firestream/Ballast/GravityWell, a group averaging DPS doing as low as 120 could still beat the 12 minute enrage.

Turn4 is where DPS really begins to matter and pretty much everyone needs to be at or above 200dps.
