I actually did the remap and I have to say I am pleased with it. I had 95% in space before and I can still get nearly the same build for space. As for ground I now actually have some decent stats as well.
I also think the new Skills window is great.
For the doom and gloom faction I can only say: Actually do the remap and you'll see space skills only got nerfed the tinyest bit thanks to the new skill costs.
