Yeah, I'm definitly not ready to quite, and I know what you mean about you, a couple of other posters and me being completely hooked by the content (just look at that deathwing post lol). I do love it all, but I hate lvl'ing, and I am comfortable with the monthly fee and understand its need and I support that, but it's still somewhat of an investment.
I am pretty impatient i guess, and I am lazyish, it's just I want my hero classes already, much more than i wanna be lvl 80 (I always said my mage (as his my favourite char) would only be complete at lvl 100 epiced out). I'm just dreading the dark side of lvling, but also rejoicing on all the new content we'll get to experience. as far as I've played warcraft (not just WoW), I've always wanted to confront Ner'Zhul. The one I really wanna test myself against being of course (being a mage you'll understand) Medivh :-) (deafeating Krasus in a duel would make me happy too).
So yea, don't expect not to see me around for let's say at least another two year, then we'll see I guess...
