I'm new to FFXIV but I'm a long time player of games like WoW, Rift, Asheron's Call. I am playing an arcanist and I only just found out through some reading that you get jobs which gives you a new class. I'm assuming when I hit 30 I want to level an archer to 15 and then go summoner? In WoW I played a mage and had a warlock alt so I really enjoy caster dps. Is there some quest to go get at 30 or do I have to level another class to 15 first?
