I've never posted anything in the Red Mage forum, but I've been sitting here reading the update and looking at job capabilities as they are and all I can come to a conclusion: RDM/SCH is going to be a good, maybe the best, party/HNM/Event combination for level 80.
RDM/SCH is going to hit Fast Cast caps... (Already does)
RDM/SCH lower MP costs.
RDM/SCH will have access to Parsimony, and now we have Tier 4 Nukes on RDM. (Water and Stone 4)
RDM/SCH will have access to Erase(ga), Reraise(ga), Drain, Aspir, Hastega, Dispelga, Protect 5(ga), Regen 2(ga) and Refreshga at lv80.
RDM/SCH can use Composure and Accession, thus question that remains to be answered is will the lengthened enhancing magic effect extend to the entire party.
This is going to cramp your macros, and some people may find this combo too labor intensive, but I think it will be worth it.
^ This is just what I've been looking at I'm sure there is more.
