I agree with you and from the EA, their innate abilities (Mosquito Swarm, Poison dart, fireball etc.) are very strong at level 8 with 10 in summoning. Might even be stronger than your regular wizard, they just have only one spell to cast.
However I still think totems are almost too strong because of the sheer amount of target it gives the AI to waster action points on.
But I agree 100% about the incarnate and I actually was one of the rare person saying that Incarnates seem to get very strong at certain skill level, because not many had spent enough points in the skill.
