You didnt play like 2/3 monthes and you ask if you should come back?

If you quit in the first place because you got bored, there is nothing to come back for yet... wait untill wrath of the lich comes out or something... than you'll have lots of new stuff to explore.

I quit before BC, after year and few monthes Im back now because there is outland to explore I never been to and there is also new exp coming. New patches does not sounds interesting enough to come back to wow if you were bored from the game before you quit... imo.

Pfff... didnt 7.7.07 teach you a thing? By downloading things online instead, you save earth resources needed to make/import CDs to shops :P

But anyway, I dont mind downloading stuff... its sure done that way that if your system "breaks" you can redownload.
