How difficult is it to run dungeons as classes, not jobs?

[Mysteltain]

CM and Prae are sufficiently trivial that, a full party of people in AK/DL gear with their Garuda or Titan weapons (can't Relic, they're job-bound) will absolutely wreck them even using classes instead of jobs.

I'd be more impressed if they managed, say. Turn 1 of BC.

Well, if they're in sufficiently well-melded, HQ 2* gear with HQ level-70 crafted weapon (I say this just because I prefer the look of those weapons over the Primal's, heh), I think it's feasible. Hard as hell, sure, but feasible. Then again, my experience only goes up to HM Titan, so who knows. If I run Coil later this week my opinion may change, but until then I can only speculate.

And I know we're getting pretty theoretical, but I just love thinking about this kind of stuff--the unconventional ways of going about playing a game. Like in DMC3, hardly anyone I talked to used Nevan (the guitar weapon), but under the proper circumstances it makes you damn near untouchable while looking cool as hell. Or when I played Ragnarok Online, people never bothered with the Ninja class outside of spamming this one ice spell it had. But I went for its stealth abilities and found them pretty damn good, if requiring good gear and skill. I just try to not write these sort of things off until I try them--the hard part is getting others to play along =P
