..in my mind would be to alter the structure of tourny events.
At the moment some builds excel because the only objective is to 'kill everything'.
If like in 40k tournaments i've ran in the past there were around six different scenarios you could play (that you rolled before playing each round) then you'd have to take a force capable of a wide variety of roles.
It would be no use taking something entirely sluggish and with loads of firepower if one of the scenarios required you to jet around collecting message pods etc.
I think if FFG made the tournament scenarios more diverse you'd see a corresponding diversity in list builds as you'd be stupid to rely on 'one trick ponies'.
