As someone pointed out, if they just called it Diablo Online there'd be absolutely nothing to whine about. From looking at the details, it appears they *do* want a more MMORPG-like experience from the game.
Which is fine for them I guess, but not what I played it for.
I tried Diablo 2 multiplayer once or twice. It was a disaster. Lag and rubber-banding were miserable. It wasn't fun. I quickly reached a 'never again' decision and went back to enjoying my game. My other half, who had nothing better to do at the time, contemplated spending years on the online games trying to obtain rare weapons to sell on ebay. I looked baffled at the idea.
It's been a long long time since Diablo2 and I'd pretty much given up on them ever releasing 3 and/or doing anything interesting with it. So I lose nothing by the realisation that their eventual release is the opposite of what I want. In the time between, I've played FATE and Titan Quest and really *should* get around to Torchlight and gosh did I never actually buy Din's Curse? I should do that!
So yeah. No real loss. :)
