It seems that's the 'tutorial' tooltip you get when you reroll a new mage now and you choose for the first time a spec nowadays so it seems it's a design decision to make frost "the default" and the other two the niches, while frost was pvp dominating and fire pve and arcane niche-pve in the past, it seems to go to another direction now. Is there any official statement showing an official Devs stance on that kind of thing, showing if they have decided to make frost "the default" and why?
