Lame and Lame. They seem to want to make every creature a playable race, even going so far as to create new ones for no apparent reason. This does not sit well with me, don't really have a logical reason why but I find it detracts from the game feel in a big way.
Not to mention shardminds seem to be ridiculously tailored for a min maxer. Awesome ability to resist hunger or drowning or other endurance related challenges and they have a feat that gives them +2 Damage which scales with tier to any psionic attack they use. This seems similar to weapon focus but superior in every way. Smacks of a lack of balance and/or consistency to me.
