A new player cannot play BLU. They require CoP to get all their spells. Found this out the hard way and started all over again.
Affording isn't a problem, I'm farming my ass off like I said.
And your logic escapes me: please at the very least explain your reasoning behind "Don't play the job if you don't want all the parts".
My reasoning is simple. I don't want to waste time, I have no plans to play a damage dealer, a tank or a black mage, I do however have great interest is having a puppet that heals me.
