I realize I should just shut up and level my BLM one more level and go as that someday, but I'm still not seeing the uselessness in a RDM...
RDM/WHM:
---WHM/30's have Cure III at level 30. RDM/30's do too.
---WHM and RDM both have Divine Seal.
RDM/BLM:
---Now let's get something straight. At level 30, a BLM and RDM are still almost as good nukers. Only advantage is BLM have Magic Attack Bonus and 2 of the Tier-II spells by then. Especially as a Taru, I didnt see resists on my nukes until the early-mid 40's. We can still act as nukers at 30.
RDM's and what they can do others cant:
Im not sure on the boss's vunerability to magic, but seeing as everyone likes BLM's for promyvions, probably means they cant handle it so, RDMs can most effectively cripple the enemy with enfeebling magic. Im sure the bosses arent as hard when theyre Slowed, Paralyzed, and Blinded.
Chainspell and how it effects you:
A lot of people underestimate Chainspell. Should the need arrive, I can cast about 45 spells in 45 seconds with it. How useful is that? Well when certain Crayon's in Quicksand Caves pull 2 Anticans at once and then accidentally engage a beetle, well lets just say I took care of that. Chainspell is really powerful, and with a yag drink and maybe an High-Ether (I know it wastes 10 seconds of the two hour, but thats still 35spells in 35 seconds) Im sure I could get off 1000+ damage in under 35 seconds. BLM 2-hr? Please! If you brought the meds and juices youre -supposed to have anyways-, you should never need free MP. Only thing Ive ever used Manafont for on my BLM is for the "Spells Cannot be interupted" effect it also has, because Im going to intentionally overnuke and keep nuking once hates on me. But then again, that same "Spells cannot be interupted effect" is also given by another 2-hour...Chainspell!
If you still think RDM suck, just invite my BLM...no skin off my bones. But Id like people to stop doing cookie cutter PTs for everything.
