I agree with Skarphald so much in his above post. There are so many ways for the classes to deal with things, aoe, cc. Having barrels of oil, puddles of acid, all that stuff already there to be used, just takes any tactics out of fights. It also takes away from the uniqueness of the classes. You dont have to think of a way to deal with the situation, its already been put there for you. An interactive environment is great up to a point, but too much of it just gets repetitive and not really fun.
