Warriors have it relatively easy, as they get their tanking stance at 30. Wait until you go back there as a paladin and it's ten levels until you get Shield Oath, and things will be a lot more "interesting"...

It's not an especially difficult dungeon, but it's probably the first one where it's really easy to accidentally over-pull, and there are parts with a lot of adds and a lot of AOE attacks that you have to dance around while being careful not to aggro extra mobs. Sounds like you had a decent group as well - the concept of running to the tank when you get aggro is completely alien to most players - which is always nice.
