This is an elemental wizad with some wacky class powers.  Only one bonus feat, and no familiar, but the ability to metamagic up to 6 spells permenently w/out changing their level.  This class has access to a lot of powerful high level spells.  Less flex than a wizard, but still gamebreaking.

I recommend - Tier 2

I agree. Due to its limitation, I considered calling it Tier 3 untill I noticed the potency of it's 9th level spells. I concour with Tier 2
