just got my almace to 85 recently and i can say that if they just made CdC questable (so you didn't NEED to go through all that emp crap) it would go a long way to helping rdm melee.
as is right now, i can keep up with most NON emp holding jobs dmg-wise, (just going by my limited experience of course)and i can even compete with the emp holding thf in our ls. (course that's just a thf, but i'm just a red mage, so...) all that with my melee set still far from optimized.
of course my damage suffers against anything SERIOUS, casting burden and all, but i think that's about where i "should" be as an rdm. if anything i'm a little op now in pt play.. all i have to do is stop casting to become a "real" dd, and it's not like i haven't been gear swapping everything but weapons ANYWAY since qufim, so it's not like my spells have suffered much at all. (but again.. i had to get an emp weapon to get here. so maybe it's justified if i'm a little op)
obviously i can't estimate how much dmg i'd be doing using CdC with my old shamshir+2 or something, but the ws itself is a pretty significant buff compared to death blossom. if it were practical to attain it would be a big deal, and might get rdm to about where it belongs.
as sun has been saying... if, instead of cdc, they added a powerful elemental ws NATIVE to rdm, that would mainly fill the same role, and even "gimp" /nin a little bit.
