I don't see that 3d8 is too obscene, though it is on the powerful side, I'll admit. He's also at -2 to hit and -2 to AC, as well.
And the Wilder, who possessing 1/2 a brain burns a feat to pick up the ability to summon astral constructs... With the ability thusly to produce summoned creatures 1 or 2 levels higher than rationality would indicate.
That's not a huge issue to me, because of (A) the rarity of summoned creatures in the party as it is, and (B) the enervation chance that means that for every two or three times per game this is tried, there is a GOOD chance of burnout.
THEN, a couple of agreements...
Telepaths, the ability to belt out 3 spells a round.
One of which is six levels low, but I do agree on this point. If they took pain to fix this in 3.5, it should have STAYED fixed.
Kineticists, with a "Fire Platform" capability that would put any mage to shame.
I would have liked to see the variable element effects as feats, true. The ability to spit out ANYTHING from cold to fire to acid to sonic to electricity is WAAAY too flexible without additional cost - say, each psion chooses an element type to be familiar with, and they must take a feat per element type after the first one chosen. It's not like they don't have the extra feats to use, and it's not like they energy types aren't worth it.
