I still think it depends on the person.
As Leona said, the person was fine at first ... if he kept on being fine like that then all would've turned out well enough.
There are some people that don't know how to play their characters, whether it was out of plvling or not I don't know. But to be like that, they would rather have not read anything, no guides at all or have been plvled from 0x (as that was where most of the tutorials/stupid mistakes could be learnt).
I don't think plvling is necessarily an entirely bad thing, but of course that's biased in my opinion. In times when I felt bored plvling pulled me out of boredom.
But yeah, plvled and then not knowing what to do is just not that great. I mean, you're not going to get plvled all the way to lvl 50, right? Better to start learning your character right.
