Unarmed is great... when you need to kick ♥♥♥♥♥♥♥ greydwarf out of you house and dont want to crash your furniture. I mean the middle button attack...

Just do not bother about skill level - this is my advice. You dont want to die in this game, but you will. And trying to regain skills back on easy targets is a wasting of time. There's almost no difference between 50 and 55, so just stop to think of it (sorry for my eng).
