That's not really core is it?
...
Now, you have asked me to stop debating and post a build. I would like to ask you to do the same; would you kindly make an elan psion with SRD/XPH psionics and show me how it's done? After all, as you seem to know more than me - and the entirety of the character optimization community - about how broken the psionics system is, I trust you will be able to demonstrate your learning and put all doubt away?
Oh, come on! I'm no optimizer. It would take me ages, I'm probably bad at at... and lets face it, you would destroy me.
But putting builds in the ring is not the only way to criticize whether something is broken.
Moreover, what I find a bit confusing is your view (and I don't think that I 'm taking a wild guess here), that only optimizers can really know what's balanced and what isn't.
Most players out there are not into min-maxing.
Either the don't like it, or they are just not good at at... or they just don't have the time to spend.
Whatever the case, those people are fully capable of being judgmental in respect to balance, and being right at that...
Why?
Because by digging up an unbelievably broken combo, (be that even if its an SRD combo only), and by setting it/baptizing it as "the most powerful thing ever" does not mean that anything else bellow it is "balanced".
Apart from broken "combos" there are also plenty of broken stuff in the books that do not have to be optimally combined so as to prove their worth. Sometime's its the obvious choice the rookie player will make... Sometimes its the single choice of a single PrC, a single feat and so on.... I hope I'm getting my point across.
If you feel that my refusal to post builds proves you've won, or that you are right, then I gracefully bow before your grace and hand you the 1st prize cup.
As far as Elans go, I've made my points in my previous post, and that is as far as I'm willing to go to prove how they shouldn't be a LA+0 race.
Sorry to disappoint you by not posting a build.
