At 51 in old style XP parties you needed the m.acc from staves. At 75 it was largely unnecessary unless the target was highly resistant to that particular element. Mostly it's been used as a fake argument by the anti-melee crowd to get a sword out of the RDM's hands. We have 0 staff skill, forcing us to wield a staff prevents us from engaging the monster, thus they auto-win the debate by using that as an argument. Now we have so much +skill to go with our base stats that accuracy isn't an issue anymore. It's that the NM's have built in resistance to anything that counts, and nothing you do will overcome that. I've done double +50 m.acc atma's and 400+ enfeebling skill and stuff has still resisted things like para / silence / bind / grav / sleep and sometimes addle and slow (depending on the NM's alignment). It's just what SE does to NM's, they make them immune to most things. The most common enfeebles that I've used are Slow II and Dia III.
Therondy?

Well...not, us. Meant at the Blms loling at it.

But yeah, other then stealing Brds chance at a grellow party not much lol.
So messed up that BLM's 10min JA is used to proc a spell from a sub. That speaks volumes about how "useful" it is for anyone else.
