I -think- they are trying to give some of this to all casters in MoP, at least I felt more like a mage on my Ele than before in this regard, same on my moonkin. But I kind of agree with you that if you want to just pug BG's and such without friends, Mage gives a lot less frustration than the others. Annoyingly I prefer some of the others so I go in with the possible frustration in mind. :P
