Improved Missions

I read a piece somewhere saying that the next improvement for AO is an improved look to missions, and that got me to thinking. I don't know if this is what's planned or not, but this is what I'd like to see.

Missions that look like the new Subway Dungeon, and the new "Will to Fight" Dungeon.

That is, using the larger rooms and halls as the pieces, rather than the cramped spaces in the current missions.

It'd solve pet pathing issues and make missions interesting all in one swell foop.
