I said to myself that I wouldn't post in this thread but why start listening to myself now...

I supported the nerfed FF system (mainly because I was glad to see the list developing) until heavily playtesting the list with a player that I beat about 60-70% of the time. He plays Marines. Once his winning streak went to 6 games I knew there was a problem (that said, we were playtesting the list and so some situations and army builds were not ideal).
I then proposed that we change the FF values to reflect the real Tau firepower at short range and use an activation modifier to help shape the Tau playstyle (exactly the same way that Orks have done from the beginning). This was criticised and rejected (mostly, I believe because the process was too far down the road for there to be change as big as this one). Comments like "why would an army be great at FF range fighting and not want to use that firepower..." etc. What's odder to me is anyone that looks at a Crisis Suit stats and can possibly think that 5+ is even close to realistic (and why a Krootox has a better FF than a Crisis Suit ...

).
Tau have the most amazing firepower at short range. They try not to let the battle get that close as they do have a high value on assets. That said, anyone that actually reads all the available fluff on Tau will see that they are not afraid to get into a firefight if the strategic need is there and they certainly are happy to dig in and let a foe rush into their guns and get mowed down. 5+ FF does not allow the Tau to dig in and hold objectives. Epic Armageddon is often won or lost on the outcome of engagements. Tau should be better at FF engagements than they are in the current list.
I don't expect any change as the current list seems to be basically balanced. I'm sad that it's not a more Tau representative list.
