Maraudon used to be one of the longest instances around, a twisty place of corruption and centaurs, filled with quests and strange stories. Now it's possibly the worst instance. [since writing this I've done RFC and have to say, it takes the prize. But it may merely be that post-patch lowbie instances are a miserable boring experience.]
The butchering split it into three parts in the dungeon finder. These parts are less than the whole, literally. Between the end of purple/orange and the start of pristine waters is another boss and a quest. To complete these a player either needs to convince an inner group to loop back or a purple/orange group to not leave the second the completion pops up. The first seems the easiest, since it just means a slight diversion rather than changing the habit of dropping the second the boss is dead and looted.
It gets worse though. Past the last boss of inner, the Princess, are two more bosses: a crocolisk and a goblin. There's a decent chance that people will still fight the crocolisk. It's literally a jump away from the last boss. But the goblin, well people often didn't do him back when we actually stuck around in groups, so now, there's not a chance.
I can understand the drive for shorter instances. But I have to wonder, and this is going to have to be a post of its own someday, is butchering content so everyone can see it a good idea? In this particular case, people aren't even seeing the content. Two bosses are pushed out, a quest along with it, and thanks to the teleport people cannot do the quests that require actions outside the instance portals. Though this is partially fixed by the discovery requirement.
On the plus side, I have heard rumors that they're putting it together better, though I don't know if that's an upcoming patch or cataclysm. Maybe Blizzard will learn something from the LK instance experience. I'm afraid though, that signs point toward it being the wrong lesson. After all, random groups for random places for badges and shards sure was popular, so it must be good.
