I forgot about it, but hands down the worst thing about Pokebank not being updated until 2 months after Sun/Moon's launch is there's a lot of Egg Moves we can't get until then.

Just a few examples from what I saw looking things up on my own:

Rowlet can't get Curse or Ominous Wind.
Grubbin can't get Electroweb.
Crabrawler can't get Superpower.
Dewpider can't get Power Split.
Salandit can't get Belch or Knock Off.
Bounsweet can't get Feint or Acupressure.
Sandygast can't get Ancient Power.

Again, those are just some that I looked up, and very few of those are gamechangers, but it seems safe to say that most of the new Pokemon have at least one egg move they can't legally get until mid-January.
