What a year so far: We've already gotten or will be introduced to DCS, Hero powers, Items, Difficulty Slider, Story mode revamps, and even "Infinity system" soon.
With all these potentially seismic changes, I think the next logical step would be reviewing / updating all enemy powers, affixes, and animations, group by group for each type.
Apparently a lot of things have to be considered what Rogue's stolen powers would look like should such changes happen; and I am aware some of the bosses (e.g. Shocker) have been given a new move or two.
Nonetheless, all the bosses and enemy mobs have been using more or less the same powers for... a very long time, I guess.
I just wonder if this is something in the pipeline too, perhaps for next year.
