During alpha (or maybe closed beta, i'm not sure), there were some powers that didn't make it in the final version of the game. It's a shame cos they were pretty cool.
I can only remember two of them:
-Uppercut had an advantage that would turn it into a dragon punch, which could be followed by another punch attack that would slam the target to the ground.
-Thunderbolt lunge was a kind of "claw lunge", your toon would sumersault several times and finish in a stab position, with the claws appearing.

I think also power armor had an energy builder that didn't look like you're trying to catch a goat, and there must have been others
