Unfortunately, I do feel FFXI is superior in this regard. The sub-job system just felt far more compelling than what we have here. Yeah... yeah yeah, you had your standard setups that were "mandated" by the community. However, it also allowed for some fun, quirky, and the occasional, "WTH, this shouldn't work but it does and it is really fun!". Most cross class abilities are basically short-term buffs and nothing more (exception of a few spells from DoMs).
