Are you using many short term consumables? e.g. crit pots, wrathful flames, energy pots.
How many chloros are you using?
Is your raid timing debuffs together on the boss, e.g Flaring power with a wild growth
Atm our rogues only hit 4k on Ituziel with the ID gun, so I'm trying to figure out if theres something we're missing on raid buffs, or personal consumables.
