Kara was never so much "big" as... it had... soooo many floors............... good times RPing there after clearing it, though...
Maps should be released with the Raid/Instance, they're just being lazy.
I would love to see Blizz bring back Kara the way they are doing ZG/ZA. It would be interesting to see how they would do so considering how large an area Kara covers.
There's been talks of a Lower Karazhan hasn't there?
