To be fair to you....mages AND shamans have probably been the two class's receiving the less care and effort put into enriching their experience. That being said, it doesn't really justify resenting mages because their turn has come. Yes they are being given bloodlust but surely If you are as you say in a top 50 guild since Vanilla you are very well aware that shamans bring so much more than just the 40 seconds of lol once a fight..as for the new argent defender type spell, with the raiding experience you put forward, surely you can see the benefit of extra survivability for the squishies and how it will actually HELP in your raids (bigger picture
). Also i seem to recall some pretty cool changes announced for resto. I can only presume that you are an enh or ele shaman upset before even knowing what super fun changes might still be to come.
Now sadly you speak of the bigger picture being equality...my good man the word you should be using is homogenization. Like it or not that is the direction developers have chosen and the one wow is very firmly set on following. I repeat myself but it seems to be the key point you are missing : Bring-the-player-not-the-class.
