I guess I'm the kind of guy who reads this thread and thinks, "Why not just pick a race/class combo that you want, regardless of edition, and ask the GM if you can simply optimize the race in your case for the class, so you aren't left behind on the battlefield.
Case in point (I'm talking about 4ED&D) Make a Goliath Psion because you think it would be cool, and take the Goliath's +2 to Strength and Con and make it a +2 to Int and Wisdom or Charisma, instead.
Doesn't it make sense that your Goliath became a Psion because he was oddly suited for it? Maybe your character is the odd one out of the race or maybe you just ignore that technicality and play the game.
That would make Humans by far the weakest race, then. I guess if you gave humans +2 to any 2 stats to match up with your non-humans getting the same, it'd work out.
