How to counter Tau?

[Koremu]

I'd drop Terminators entirely. In fact, I'd keep everything as standard as possible and simply go forward with as many units as possible. The Tau frequently lose to a saturation attack because they can't do all their funky stuff to all those units simultaneously.

 

Bikes are good too. They will inevitably get shot up, because the Tau player has to shoot them up or die, but then any survivors will make a mess and the Rhinos will be getting closer.

 

Also, Chaplains make you immune to pinning (as do the Bikes Turbo-Boosters, tbf).
