So, as a World of Warcraft player and a person who follows the gaming world fairly closely, I tend to read a lot of forums. With the upcoming 2.4 content patch currently on the Public Test Realms (hereafter referred to as PTR), the WoW Test Realm Forum (found here) is a great place to see how players are liking the upcoming content and class changes.
Judging from the forum posts I have seen, one of the more controversial changes coming in the 2.4 patch is the removal of attunements for the Mount Hyjal and Black Temple 25-man raid instances, and the introduction of gear that can be purchased with Badges of Justice that is on par with Hyjal/Black Temple drops. At first glance, the non-MMO player would wonder why this, of all things, would be a point of contention. Personally, I wonder what mindset makes players think this is a bad idea.
