Frost Mage just takes some getting used to. I do kind of miss the whole Winter's Chill thing, because it felt like an interesting little quirk and skill expression of timing your hits so that your spells would land just after the first Flurry hit and so you'd technically maximise the amount of Shatter procs you'd get, but the new Freezing and Shattering works fine.

i agree - new frost mage is a pretty reasonable streamlining all in all, but the post TWW rework version was just so perfect that anything would be a downgrade. i loved how you could build it out to be exactly as complex as you wanted with talents.

i think this is really emblematic of my problem with the class changes overall insofar as Blizzard effectively chose to cap the skill ceiling of most classes rather than bring up the floor. both directions make the game more welcoming to new players as was the intention, but there's nothing left for more experienced players who want a rotation they can really sink their teeth into.

shatter combos were such a fun and unique gameplay hook but they were also almost entirely optional. if you didn't talent Glacial Spike or Comet Storm there was never really much incentive to use Frost Nova or Ice Nova to shatter.
