This is where the developers are supposed to make interesting creature behaviours. I mean more than just standing around, attacking anything that enters their aggro zone.
They're a subscription game. I like open areas. Coruscant is horrible. Neither are particulary interesting though, when enemies are evenly distributed, often 3 enemy types in a given area, and they just stand around, or pherhaps move a little.
Skyrim had some interesting behaviours (Giants, fox, rabbit etc), and it really helped make the world feel more alive.
Today's mmo's don't have an interesting wilderness. They have grinding fields. You could make enemies more evasive.
I remember in STALKER generic quests could be highly entertaining because of the dynamic world. Things would occur, and I would have to adapt to that.
