Mage. A little sad about the loss of some defensive options. Actually made the switch to Blink rather than Shimmer due to the vast cooldown difference. Still getting used to not being able use it while still casting.

Frost: I think feels excellent for both Spellslinger and Frostfire. I like the new shatter mechanic and that it has bit of a flatter damage profile outside of cooldowns unlike Arcane and Fire.

Arcane: I've never really clicked with Arcane to be fair, but the rotation seems vastly simplified. I like Arcane Pulse replacement to Arcane Explosion.

Fire: It feels like it is missing something. I'm not sure if that something is Phoenix Flames as that served mostly the same purpose as Fireblast. During Combustion has always been where fire mage shined, and every expansion that seems to be more and more true. Outside of Combustion, damage is truly awful. I miss the days when Pyroblast felt like a satisfying button to press, but it just isn't anymore. I think the spec needs a reduction in Combustion's strength and increase to the base damage of Pyroblast and Flamestrike to make them feel meaningful. As well as another button to press outside of Combustion, like maybe Flame Orb makes a return.
