No seriously. Blowing all your gil on abilities that are *KEY* to your job (read: sleepga, utsusemi, obscure ancient magics) was not something FFXI did right. Also mage weapon skills were stupid as well. Last thing we need is more "it's okay guys, I'm melee red mage / winja".
If you're wanting to work for your abilities, you're going to get that chance. The job system is going to require questing to unlock the full potentials of each.
