One round results and fifty round battles - both were/are undesirable. Balancing such a strategic game is not an easy task; although it may be required in the long run.
I too feel like it.. but there culd be so many possible combinations of race-specialty-attributes-weapons-skills-strategies that every time there could be a build with different outcome than we expected and we might feel like if we could respec once again.
However, I would sincerely request Nate to please let unlearning not too hard for us; so that we may be able to experiment with different skill sets in addition to fight strategies and gear; this may ultimately add to replayability of the game.
