Maps do not have to be done with class you want Alex for... So if you have troubles killing bosses with one class, just pick another. I have been able to solo(no friends or chocobo) all of the mobs with WAR. While I haven't tried it I see no reason why it can't be done as SMN with pet and choco out. can swap to DPS pet for adds as the cyclops is far to busy casting AOEs to really need a tank. Bane on adds with shadow flare should get most while pet deal with the rest. Choco will either be healing or stuck on boss depending on setup. Sounds pretty easy... And that's not even counting cross class skills.
