I hate how I can play any spec I want on any class I want and be able to perform in PVP, PVE or solo effectively. I miss having to heal when I didn't want to or tank because that's the only spec that's useful for my class. That made the game better.
This is how those people sound every time. The game continues to get better and when Blizzard gives people what they want, they complain about it because they're stupid and don't have a clue what they're talking about. Case in point with dailies. The #1 whine I saw for months and years was "AMG THEY IS CATERIN TO THE CASUALS" by letting you simply walk into raids, get gear with vp or LFR. Now you...have to do something before doing that. Something easy that you can do on your own whenever the hell you feel like it. It seems that these so-called 'hardcore raiders' only wanted other people to do the work, not themselves.
