From my perspective the quality of their games is declining. Rapidly.

I don't know the author and his gaming background but he certainly hasn't spent much time playing blizzard games. At least he isn't a 'hardcore' gamer. Truth is, if you are a casual gamer you probably won't notice how dumb their current development is.

In short: WoW: Numbers don't lie. People would still play mmos if there werent any worth playing. http://www.mmo-champion.com/content/5063-WoW-Down-to-5-6-Mil...

Diablo: Current content is shit, multiple design failes that needed to be corrected. Both D3 and the addon weren't ready on release, needed patches to correct the bad quality.

Hots/Hearthstone/Overwatch: Knockoffs of Dota/LoL, Magic, Team Fortress. I don't think a knockoff should be called a quality game. Also, both Hots and Hearthstone have/has horrible balancing issues => bad quality considering being balanced is the core content of the game. Not to mention that Hots was really shitty from a technical pov (after beta).

Regardless of your personal opinion on the design of their games, one thing they retain is their quality. Blizzard games are some of the most polished bug free experiences available (especially given their scope/size). You are never going to have a poor experience with a Blizzard game.

You might not enjoy the game, but it will not be because of game breaking bugs, poorly translated ports, low art quality, or unpolished game systems. Blizzard takes these things very seriously. If something is broken they often fix it.
