Arcane Fire is weird, but I know one Fire and Ice wizard in my group who's going to absolutely love it. She likes to open the fight with a big explosion, and this will feed right into that strategy.
Dual Implement Spellcaster is pretty clearly awesome. I wonder if its going to apply to all targets of attacks, including area of effect attacks. If so, that's a pretty serious damage bonus. Leaves existing damage bonus feats in the dust once its had some time to scale.
Arcane Reserve is pretty awesome. I'm liking the "get a bonus once you exhaust stuff" theme that human feats are starting to have.
Draconic Spellcaster makes me happy. I'm all about theming spellcasters. I hate the tendency towards generic wizards.
Twist the Arcane Fabric is pretty neat, but might start to become redundant with all the other options for making your area powers not hit your allies. Still, it works.
Reckless Curse is pretty amazing, since with intelligent play, its probably a straight, stackable +1 to attacks.
Destructive Wizardry is nice! Subtly powers up Scorching Burst, incidentally.
Enlarge Spell also subtly powers up Scorching Burst. I look for this to be an often neglected feat cherished by the elite wizard players. Its rare for -2 damage to be a bigger penalty than getting another target into an area of effect, and once you hit paragon tier your powers have little friendly fire risk anyway. And at epic you might even have none. So go for it.
