Just a quick comment on Blm nuking in emnity gear over max dmg or max skill gear...
If your doing that than your one of a couple things.. Either your highly ignorant, or your using a (not so) justifiable reason for having gimp gear. Excuses such as.. your tank could be bad.., or you do too much dmg in max dmg gear, or you just have to plain 'watch' your emnity are not reasons to use emnity gear. Those situations are reasons to use lower tier spells, such as using tier3 instead of tier4/AM2 and spacing out your nukes more. You could argue that by reducing emnity you can cast more instead of spacing out your nukes, but you have to keep in mind all that your sacrificing when you do that.
Lets try stacking on Emnity gear because your tank sux when your fighting an HNM. Good luck getting any dmg done. I know we weren'ttalking specifically about HNM's so I wont act as though we were. The same thing applies to almost anything else, a higher dmg per nuke will always be more mp efficient meaning you could drop down a nuke tier if emnity is an issue. Not sure about you pro'emnity ppl, but I'd rather have almost every nuke count than be shooting blanks because of lower skill.
Though I don't have blm75 I do have Sch75 and when I'm nuking I would never sacrifice my dmg or resist rate for the sake of emnity. You need all the skill and dmg possible to make all your mp worth its use.
