[quote:5649acbbdd="madox"]I have a strange feeling that with Blizzard making Heroics, Kara, etc easier to  enter. 

That you will need those items to step into the continent for the new Expansion. (wraith of the frost guy)

I bet lvl 70+ will be tough without those epics.

I doubt it really, if Wrath of the Lich King follows burning crusade.  You can be level 58 in quest greens and start into outlands (like I'm going to do tonight!).
