I generally agree with this, but specifically I want to recommend against "Do nothing". "Do nothing" is a terrible "you're taking too long" action. All Out Defense or Evaluate or even Wait are better options, as the player doesn't feel punished afterwards.

But definitely strongly recommend making sure there's a clear "Bread And Butter" attack for each PC. These are like the At Will attacks in D&D4e - things you'll do a lot that are always reasonable choices. The risk-reward ratio is decent with no special risk of loosing a limited-uses ability on a bad choice (or in GURPS, FP and other combat resources). These shouldn't be the "also ran" colourless ability like "Swing weapon at torso", it should be something decent but not-too-complicated.
