I agree on the initial point; it's not about the difference between playing a perfect game and building an imperfect one, it's the difference between playing a game and finishing one.
Other than that
A) Battle would be be more difficult (Read: Interesting) if they bothered to make it more strategic, I've given various examples of how they can do this around the forum, not gonna get into it again.
B) Screw you and everyone who thinks that aggro icons make it too easy; no one likes running through an area and getting one shotted and forced back thirty minutes worth of holding up/w because some monster decided he didn't like your hairdo and felt the need to convey the hatred it brought forth from a hundred feet away thus leaving you wondering why you're suddenly dead. No one. The aggro icons were a good idea and they better damn well stay.
If you like living dangerous, then ask for an option to turn them off. But by the time you feel that way, chances are you're already going to be an experienced enough player to know which is which.
