As for specifics on the class....

Agreed, overpowered. Wizard bonus feat progression + Wizard's spell access + much of the Sorceror's flexibility + two stats to DC's? At lower levels, that will work out okay, due to the lower base dc... but once that character gets to the point where both a Headband of Intellect and Periapt of Wisdom are feasable, DC's will get out of control rather quickly. Consider that in order for a normal wizard to increase spell DC's by +2 the wizard must invest in an extra +4 of enhancement to Int (16,000 gp); a Cleric, Paladin, Ranger, or Druid, +4 enhancement to Wis (16,000 gp, again); a Sorceror or Bard, +4 to Cha (16,000 gp); this class, however, needs merely to get +2 to both Wis and Int, at 4,000 gp each (8,000 gp); half the price. For +3, the Elementalist needs to spend only 20,000 (one 16,000 +4 item, one 4,000 +2 item) while the standard spellcasters need a maxed +6 item for 36,000 gp. The Elementalist can get +6 to his spell DC's with two +6 items (granted, for a total cost of 72,000 gp...) while the base casters have no such recourse above their +3 from enhancement bonuses. If the Elementalist manages to start with a 16 in both Int and Wis, sure, 1st level spell DC's will be a bit behind the standard spellcaster who opted for an 18 in something instead (by one point of DC). Not long after those enhanceing items are available, though....
