I have told the player that if he decides to head down the DD path (they are currently only 1st level) that I would change it to give +1 existing spell caster level every other level starting from 2nd instead of the one extra spell per day feature. I don't think it makes it too unbalancing as he will still be losing atleast 2 levels of spells by 10th level DD in exchange for the DD class abilities that I didn't think were that much greater than the elemental savant PsC that advances at +1 caster level every level.
That's similar to what I did for the DD player in my game. I gave +1 caster level at every ODD level, dropped the bonus spells, and dropped "enlargement" (a much-argued ability, anyway). I plan to allow her to grow wings, despite her size...
This has worked very well in my campaign.
