Do you still need a key to get in (on one toon) or did they remove that entirely? I wonder if I could 6 man him (3 74 mages 1 40 mage, 1 74 priest 1 74 prot paladin) I love the instance, and ran it with a couple 80s once just for kicks, and to get some upgrades to make leveling easier.

I think it would be kinda fun to start 5 manning it, and start 10 boxing with 5 80s and 5 68s, to get better looking gear (IMO the early northrend gear is fugly, the later stuff is awesome though)

If you farm kara once a week, you should be able to make some decent money, and get some decent leveling gear for alt teams

I guess you could do the same thing if an 80 DK can solo stuff there, just tag along lvl 68-70 alt teams to gear out/heal/dps a bit.

As a side note, It's a shame that the nature of such a game inevitably trivializes older content. Too bad they cant make a different "difficulty" level such as "legendary" that turns any instance into a hard version tailored to whatever level cap you are at or near... But i bet that would be way too complicated.
