No adventure, no exploration. Exploring the deep roads was my favorite part of DA, here it was reduced to one re-used corridor.
The random nr of waves of extra baddies spawning in made the combat very annoying. Never knowing how to pace or position yourself through battle with enemies spawning behind you or right on top of you. It turned it into a random hack and slash affair. I already thought there were a bit too many meaningless battles in DA, DA2 crossed the line completely. Bigger kill count != better game.
