Pretty much what Zdine said. I'm not a fan of the grind a sub-class to get anywhere myself or all in one character, class type of thing.
Since games who do that, end up as a grind fest. It's not all that bad I guess...But I see how you mean. I rather be CNJ - WHM w/o the need
to be a a ACN personally, don't care for cross-classes skills either since it still makes the main class, lack fun skills in general.
Thankfully, I'ma stick to 1or 2 classes for a while, I don't wanna go back to level 1 grind all day lol.
