I don't know if it was Activision's influence, many of the original devs moving on, or World of Warcraft coming out, but since then everything about the company seems to have changed. So much of what they do nowadays just seem like money grabs. They release pay to win content meant to be addictive, dumbed down their art style to looking like cartoons that appeal to the least common denominator, follow trends instead of doing anything innovating, and seem to have completely stopped caring about making any interesting story. The villains in Diablo 3 were comically badly written.
At some point they even tried to force users to use their REAL WORLD names on battle.net[1].
It really isn't the same company as it used to be in the early 2000's.
