So with the changes to Tau vehicles making them...well really good again, I thought I'd throw up a post of what a Hybrid Tau + Boyz army might look like. I'll do a metatransition post later, this is just for you to sink your teeth into and get discussing.
Losing firepower without the Big Guns and 10 Crisis (down to 7) but gaining some extra firepower through Hammerhead and some added durability to army with AV13 with a 3+ cover and two mobile AV12s with 2+ cover when going Flat-Out to block LoS to your army.
Potentially a different army for Allies with more firepower since there is an added defense layer here could work... Anyway, list below.
Shas'el w/Plasma Rifle, Missile Pod, Multi-tracker, BSF
2x Crisis Suits w/Plasma Rifle, Missile Pod, Multi-tracker
2x2x Crisis Suits w/TL-missile pod, 1x BSF, 1x DC w/2 gun drones
2x6x Fire Warriors w/Devilfish w/Disruption Pod
9x Fire Warriors
2x2x Broadsides w/BSF, Drone Controller, 2x Shield Drones, Leader w/Target Lock
Hammerhead w/Burst Cannons, Disruption Pod, Railgun
Big Mek w/KFF
2x20x Boyz w/Nob w/PKlaw, Bosspole
