Leveling a new character in WoW to try a new class wasn't bad at all. It's not like you had to re-do COP or anything. It was same as leveling subs in FFXI; you grind through starter areas over and over again. You didn't need to worry about gear on new classes either because if you had 1 class leveled up fairly high, you had all the gold you need to pimp out a new lowbie class, or if you go cheap, usable gear drops from regular mobs as you quest along in WoW.
Actually I wish FFXI was easier to level a whole new character. If I didn't have to go through the whole ordeal of rep grinding, money on bag slots and gear, nm camping for r/e gear, CoP, ZM, Airship passes, etc I would level a couple characters to be more job specific. It would be nice to be able to use all of the merits that would improve the jobs. Like maxing enmity, HP, sword, shield for a pld character. Then having a blm with max -enmity, mp, INT, etc. The limit on merits limits you to either 1 pimped out job or a couple not quite pimped out jobs.
