refresh , haste : ok you cast them a lot
Yep
Protect shell : you will save like 1 or 2 mp every ... 10 hours?
Not worth it for 7 Eyes.
-na spells : get a WHM in your party
Don't need WHM for many things like Salvage(most areas/NMs..) or Nyzul Isle. Specially when RDM can just sub /WHM for the -NA spells needed. But otherwise, not using 7 Eyes for this either.
RDM can be an effective healer, do not always need a WHM(No offense WHMs out there =p).
erase : same as -na and you rarely use anyway
Same remark as above.
I hope people are smart enough to use this every time ANYTHING has any type of elemental attack or spell being casted on anyone its going to hit. But again, not worth it, since MP cost is so small.
If you do not use Regen, you are gimp. No offense, is very useful reguardless of the retardation of the spell's MP-To-HP Ratio per tick.
raise : you save 10 mp every month?
Same here, not really worth it, going to end up healing your MP anyways, because a mark of death more less means downtime anyways. And saving a few MP on Raise even if you're going to hit-and-run and keep going..not worthwhile.
Just so many jobs to be the most worthwhile, and flexible and as good as they can, alot of gears are needed...and you can not really have something like this thats not going to benifit everything instead of a few things.
Other then that, kinda agree with Pchan.
Even with the remarks being good for SCH, maybe for some things, but not enough to merit it's value. \=
IMO, if you have those extra slots, you'd be better off with a piece of gear that makes your spells more effective, whether its INT or MND or macc or skill. Effective enfeebles mean your party takes less dmg and the mob dies quicker, meaning you have to spend less MP during the party.
