I'm a little disappointed in how low the distribution of a lot of the new moves is shaping up to be.
For instance, Helioptile is seemingly the only Pokemon that can learn Electrify, a move that could've seen much better use on users like Manectric and Raichu who could abuse it for Lightningrod boosts.
IIRC, one of the developer interviews specifically mentioned that most of the new moves and such will be restricted to new Pokemon (such as Refrigerate, Parting Shot, Gale Wings, Grass Pelt, Strong Jaw, Gooey, Magician, Bulletproof, Boomburst, Freeze-Dry, Forest's Curse, Trick-or-Treat, starter moves, Noble Roar, etc).
I'd imagine they'll get wider distribution in the next game, when the newness factor wears off.
For noivern, the hidden ability telepathy (Prevents damage from team-mates during Double and Triple battles) is that just for noivern or both your pokemon on the field? also has anyone tried to put heatwave on him? noticed that he can learn flame thrower
It only protects the Pokemon with the Ability. I don't think anything compatible with Noivern can pass Heat Wave via Egg as of right now.
Would you be able use a ditto caught in a master ball to breed with a male anything and have it be 'caught' in a master ball?
Yes.
I'm guessing that there isn't a VS seeker or general way to rebattle random trainers in this game? Also, any news on the legendary birds?
There isn't, but there is Battle Chateau. The legendary bird you get depends on your starter, and can be fought at Sea Spirit's Den.
