Sacred Haven of Debauchery

Besides, I don't only play one character. I had a level 60 Warlock before – I deleted it, and I also have a level 41 Priest and a level 62 Hunter.

But the real game, at the very least starting from the Lich, takes place at the maximum level; everything else is just preparation for it. Essentially, you're not even playing right now. I can't even bring myself to criticize your character because it's not even a character as such, but just a draft for one.
