How many hours it takes?

Thanks to [MENTION=128]Stereo[/MENTION]; for the more detailed information, I wasn't sure about what kind of mules should make first.
I'm still thinking if I should delete my friend's characters, I will destroy the characters sets I have atm, but I suppose I will win something better =S...

I would keep the blaze wizard if nothing else, since it will be revamped eventually. The hero and corsair are more for if you like those characters, since they're at a relatively high level compared to everything else you have.
