While I would like to see this option, I don't expect to see this added to the game. Fortunately, traits don't amount to anything. They're really just there for the flavor. You can't gimp yourself by your choice of traits.
Meh I wanted to pickup Vulcan MiM instead of Nerve Pinch or drop Stubborn.
I am hoping they do allow at least a trait respec since you're not changing your entire race or class.
Even if it does cost a little dough.
I'm disappointed to see how useless the Nerve Pinch really is. An 8 second hold on an enemy with a 2 min cooldown; any damage interrupts the hold?! My away team usually tags the target I have Nerve Pinched, or I attempt to use it and the game just uses my cooldown and nothing happens.
It's useless, or at least I have yet to find a *good* use for it.
