Have fun with it, the story and dialogues will get pretty good after while, it's my favourite story line in GW.
Doing NM and then immediately following with HM.
And yeah, JUST spent almost two hours doing the Marketplace quest in HM. <.< It didn't even hit me to try to hide and then pull them one by one: I figured you HAD to take them head on, so I was trying to come up with a way to take some 5 or 6 HM teams at once. Did quite well with a bonder (ran daggers on my rit and I simply tanked all the teams, until one slipped away and killed off my heroes). Then I wiki'ed it and saw that folks suggest you simply hide in a corner.
Managed to do it in the first try after that. <.<
