Legitimacy when it comes to leeching?

I'll be honest, I leeched a couple levels in early 6x, just under 3. To me, I can already play my character fine, and im not leeching all the way up, but now that i've played my character around and leveled it a bunch, I know all my skills ill use for training now, so I'm more interested to get to 3rd job skills. I doubt I'll leech anymore though, its expensive.
