Support Jobbing is what makes a COR a hybrid, /WHM now makes us a hybrid healer for example. But ****, the same thing is said for all jobs. SAM/DNC is now not just a pure DD, but now a hybrid DD/healer.
Fail analogy is fail.
SAM no sub is a DD, no one argues that.
COR no sub is a hybrid DD/buffer.
DNC no sub is a hybrid DD/healer.
BRD no sub is a buffer.
Just because a job CAN sub something and become a "hybrid" doesn't make it a hybrid. The basics of the COR job is buffing and shooting. You have the option to play it another way being COR/mage, but in a EXP party, which is the frame of reference in this thread, /DNC will do just as well as /mage and retain the basics of the job.
/mage has its uses, but there are some situations where there is a much better alternative.
I guess that's why when I do a /sea COR all, I come up with 100ish names and 70ish are COR/WHM, another 20ish are COR/NIN or COR/RNG, and the final bit are COR/???. If everyone was doing it right, I think it would be more lopsided in the other direction.
You see that because people are lazy
and don't want to spend the money on bullets, not because its right
If you wanted to be COR/WHM in exp you'd be better off on BRD, because that's essentially what you're trying to be.
