Interesting. I suppose this move is likely to make the distinction between people who bought "Diablo 3" and people who bought "this new cool thing" a bit more apparent.
Having not followed the D3 development much from the moment I heard of the always-online thing, tho, can't say much. If the main complaints are "useless grind", putting more grinding in isn't a sound business decision. Oh sure, it's a sound decision to reaffirm the essence of a Diablo game, yeah, but it loses you the "appeal to a wider audience". Now, up to you if you want to have that or not of course. Overdoing it is a bad thing indeed.
