Ok, so was leveling SCH tonight, got it to 42, had a blast, etc. I was main healing, so I subbed WHM, 'cause I figured, that's what I should do.
Anyways, would SCH main heal be really hindered with BLM subbed? I didn't use Protectra...used Accession and Protect II. In hindsight, I don't really remember using anything that SCH doesn't already get on it's own. Granted, we had a RDM in the group that was enfeebling 100% of the time, and I had refresh, so that may be a consideration...
Anyways, subbing BLM would give more of a boost to MP pool (which would be nice), I'm Elvaan so my MND is already good enough in that my cures seem to do the same regardless of sub (noticed that at earlier levels), and I'd have more INT so I could contribute more to DPS when I'm not dumping heals on people (with NIN tank and Accession+Regen II wasn't doing that much curing TBH). When I was syncing to 30's, even with Dark Arts active it seemed like my cures were still doing about the same as with Light Arts.
So yeah, would it be a really bad idea to be Main Heal as SCH/BLM? Should I keep going /WHM when I know that's what I'm gonna be doing?
