It's you who changed, not Blizzard. Blizzard is the same. The most conservative game developer in the West.
I loved Orcs and Humans because of its setting but my interest in Blizzard started to disappear after I had played Warcraft 2 and its expansion. I hated the dwarf humor. I didn't like Diablo's atmosphere. When Age of Empires came out Starcraft felt like a joke. WoW looked like kindergarten compared to Dark Age of Camelot.
Not that Blizzard quality changed or anything, I just realized I don't like their clichés and cartoonish style.
The most overrated company in gaming in my opinion.
