I find pulling to be a bit cheesy, but still find myself doing it sometimes. I'd be very happy with enemies in earshot running to join a fight, even opening their own doors to do so (unless locked - which a sneaking rogue could do).
I loathe and despise kiting and hope it is not a viable tactic. In DA2 the best antagonist had the worst end as you spent half an hour kiting round him. Awful, awful gameplay, the designers of that scene should hang their heads in shame.
