I really don't like the SF ability secrecy either. If your SF have a range of 5 that is really obvious what their special ability is. The cost is significantly higher than non-SF. The only real benefit I can see is that an SF unit will be smaller and less likely to be targeted than a huge infantry unit, but it might put out similar damage.
Also, isn't mixing SF a bad thing? What is the reasoning behind hiding their special ability? This game is supposed to be light weight. How is gathering dozens of battle reports and spending hours studying them in order to /maybe/ figure out what their special ability is light weight?
