Creating a different character vs lvling alternate classes on same character?

[Urthdigger]

One advantage to leveling them all on one character that hasn't been mentioned yet is drops: When doing things like extreme mode primals or dungeons, all the loot that drops is useful to you. If you go with alts, then Murphy's Law dictates you're going to see that sword you wanted drop all the time when you're playing your marauder instead :P

Thanks for the helpful comments everyone. I will focus on one character for now and make it a melee oriented character since gear, cross class skills and lvl 30 job requirements overlap a lot among them. If i ever want to make a alt for weekly limit purposes i'll make it a caster oriented character for the same reasons.
