5.4 patch notes: http://us.battle.net/wow/en/blog/10158897
Before I start, I am going to state very clearly right now I am not arguing for or against the proposed changes. I am more concerned about the method of deployment and implementation.
There was a distinct lack of clarification for 5.4 protection paladin changes, of which there are many and tanking in general. What was posted was a general, we're going to continue to want you to use the active mitigation model but we're still going to emphasize stam/dodge/parry on tank gear, and water down your talents to justify it. Because, you know, itemization vs stat allocation is hard.
It seems to me that the changes are less of a bandage and more of a make the class (gameplay/gearing) mediocre, intentionally or not. Instead of redesigning whatever experiment that went too well or extremely poorly depending on which point of view you're taking. This is all completely a reversal of their stated intention of not making radical class changes at the end of an expansion. It does nothing but harm to the class.
It's this sort of design vision that irritates the ever living crap out of me. Instead of just flat coming out and saying, we'd like paladin tanks to work like THIS (give concrete example), it's left ambiguous. I have no problems playing the class however they intend for it to be played. I am more than happy to work towards making it work they way they want it to work, but they're not helping us help them. I'm not even sure if they know how they want the class to work at this point.
