Is this true? Good riddance.
The new Battle.net actually did a lot to damage D3 as well, probably more in my eyes than SC2, though people argue about it.
They somehow managed to completely flip the "public games are good", social mentality of Diablo 2, which drove the game's longevity. Removing chat, making private games the default option instead of open, game lists, and any kind of meaningful PVP interaction (which basically was the end game, and the reason many kept playing long after they were able to beat the PVE elements with ease) basically destroyed the game. That and weapon DPS were the two biggest errors they made IMO.
Completely shattered any sense of community.
