In Diablo 2 we had the good ol' red fallen, followed by a more powerful blue fallen, renamed carver. This continued throughout act 1, the reason being that monster difficulty should scale along with your characters power.
Now what I'm wondering, is this the case as well in Diablo 3? Are we going to see reoccurring monsters that only differ in color and name to make the game more balanced?
(Personal opinion about this: I'm not a fan.)
