don't think you're quite grasping the concept either...-30 evasion from that atma is just a drop in the bucket when your natural evasion skill is at what....376? It might not even be enough to counter just what you get from the extra agility on cruror buffs. You could probably get the same effect from gear, and not be dealing with the interference from the increased counter rate. All I know is at just 91 and running regen/regain atmas and cruor buffs, I took quite a pounding at times from those Canyon Scorps with capped skill, and the skillups were coming pretty steady for me.

With your setup, you might need to just skip Abyssea completely for that matter and just tweak your stats with gear. Not like there is a vast shortage of mobs 70+ you can pull in mass somewhere else. Have to think outside the box if what you are doing isn't working.
