Is it worth it to reroll the same class?

[Roth]

I have a 38 iksar shaman but I haven't played in a while(maybe half a year) and I feel like playing again. Is it worth it to transfer all his stuff to a new shaman of same race and class and just relevel for the sake of it? The thing is in my case, if I go back to a character that I haven't played in a long time it's hard for me to get into it as much as a character I started recently and worked up.

I would possibly even consider deleting my previous character and using the same name to save character space. Has anyone done anything like this and regretted it or felt it was worth it?
