There is no argument here. Sora is right. If you don't care to be as efficient as possible then fine, it isn't for everybody to min-max, but pointing out the best way of doing things should not be put down and most uninformed players will appreciate it.

I personally have been using 4 iron mages from Return the Field! per Odette which results in lvl 11. It's not perfect but its close enough. I get bonus same class xp, only 1 combine, and have the fodder handy from farming RtF anyway.
