The entire incarnum concept was awesome, definitely a step outside the box for our coastal arcane friends. But I too am a Psionics fan, and a well made shaper was one of my favorite classes to play.
"Oh no, we don't have food" Give him a minute
"Oh no, we need to poison the duke discreetly, but we don't have any poison." Give him a minute

I also really enjoyed the dread necromancer, although all of the games I played one in fell short of level 8 (the level a dread nec gains the ability to actually animate the dead)
