This seems to be (and always has been) some what of a contentious issue within the tau list. Trying to get a unique list that acts and feels how the tau fight in the fiction, and whilst maintain balance, has always been the goal.
I'm not saying that the current list must change, but rather thinking hypothetically, if the list does change what could we do. As there seems to be a lot of ideas circulating that have been done before (and consequently discarded.)
Previous ideas0. Currently - Low FF, increase in ranged infantry weapons
----- Simulates how the tau attack other formations without risking their lives
----- Feels un-tau like when they get massacred in FF engagements
1. Give tau defensive fire. - Essentially this gives any tau formation over-watch when being assaulted and was coupled with low FF values.
----- I think this was discarded as it was too powerful when intermingled formations were assaulted - and let to formations being very intermingled as well.
2. Discretion Over Valour - Tau units not in base to base contact are allowed to counter charge away from an assaulting unit, if this means that no Tau are with 15cm of the engaging unit the assault does not happen.
----

3. Higher FF value, -2 to engagement
----- Doesn't quite feel right that the tau are great at something but don't use that potential.

So 4 different rules that have been used in one combination or another in previous lists, all of which have been discarded for one reason or another (or are being rejected currently ^ ^ )
What completely new ideas can we think of that might work?
N1. Defensive fire - When a tau formation is assaulted by an enemy formation it gains +1 to its FF values
---- akin to the rule in V1. of the list but not quite so powerful
N2. Give small-arms (extra attack +1) to some units profiles (or some-such special rule allowing them to roll 2 dice for FF)
---- Statistically pretty much the same as just giving them +2 to FF (for a FW formation)
---- Too powerful, makes them into a FF army.
N3. In FF roll 2 dice pick highest
---- Statistically almost the same as giving the units +1 to FF (a little greater)
