Still not keen on the wild magic barbarian. They could at least have provided a tweaked Wild Magic Surge table - as it is, there are at least four options on there that have no effect if you don't have any levels in a spellcasting class.
EDIT: Totally failed to notice that they did in fact do that.
I like thew wild magic barbarian aside the magic sensing ability. That ties rather weakly on the theme and at-will magic detection is a tad annoying in play. I get that this is rather out there for a barbarian, but it fits more magical species well. I think I make this an elfling-only barbarian subclass in my setting.
I still don't like the genie warlock. I want to like it, the basic concept is definitely something I'd like to use, but the whole portable minihouse in the vessel as a low level basic ability just is way too goofy for my tastes.
