If at the end, this is the way it will be, it's not bad, but I would like more If at hit lv. 30 or 50 with (for example) Gladiator, you may unlock paladin, and level it from lv. 1.

Of course maybe SE did this this way to not make people enter in /rage Mode (that they will enter anyway) and with future jobs maybe you will need Lancer (or Dragoon) at X level, to unlock Samurai, or maybe you just will need to do a quest.

I like the fact that you need to have X Job leveld at Z level, to unlock Y job, and I like the quest unlocking method, like in FFXI, so I don't mind :P

After all, we just want the jobs we always had. It doesn't matter the way so much =)
