Leveling as mage should always, and has almost always been fastest using fire. Swap to frost if you want to play safe or need to take down a high Hp mob solo. It's the mage tank spec. Play arcane if you want something that's blisteringly simplistic to the point of wanting to blow your brains out, but its burst is high enough to accomplish the same as the other specs.
Speaking of mage, I really fucking miss being able to play hybrid specs. Arcane power+pom+pyro, or pom+flame strike with fire nova followed up with blizzard, or just loosing a frost bolt between frost nova while pummeling with fireballs and fireblasts.
The complexity has been brought back down to the simplicity of spamming a keys like a rogue in vanilla on a boss fight for everything just to make sure something is always casting, and not interesting or unique or fun in anyway. It also hardly changes between encounters, at least in Uldir. Might shift one talent here or there, but otherwise the rotation is just as generic as spamming frostbolt, but more annoying. How the fuck did that happen.
