So i had a thought. Tau have 2
HQs that buff up firewarriors rate of fire (cadre and ethereal) but the problem is unless youre against an army that wants to jump down your throat, firewarriors rarely get to shoot more than a few potshots.
This is the core of the list, the other stuff would be situation and depending on the points youre playing at:
Cadre Fireblade 60
Ethereal 50
12 Firewarriors w/ Devilfish Dedicated Transport 188
11 Firewarriors w/ Devilfish Dedicated Transport 179
11 Firewarriors w/ Devilfish Dedicated Transport 179
Total: 656
Heres the idea:
Deploy on the edge of your deployment zone, turn 1 move up 6 inches and face Devilfish's access port down the board. Disembark 6".
If: Opponent deployed at end of his/her deployment zone: Ethereal uses Storm of Fire, as you are 12-15" from whatever is in front. Prioritize troops and/or light vehicles (anything without crazy durability basically).
Then: Ethereal invokes Zephyr's Grace. Sprint firewarriors and fire snapshots.
Provided the terrain doesnt screw with this too bad, this is 60-80 Str5 Ap5 shots at BS3 hitting your opponents front line. That amount of fire WILL kill a lot of stuff. Could even have a couple groups of kroot infiltrate on the side for some additional firepower. Cadre is there to buff up one of the firewarriors even more the next turn, since the Ethereal extra shots dont stack.
Literally the goal is to strip your opponent of as many numbers as possible, not to take out big things. Big things would be dealt with by deepstriking crisis suits or backfield riptides and missilesides, which you have plenty of points for 1250-1750pt game to get these things.
Another thought: Probably want atleast 1 group of 20 Kroot and infiltrate them to make the kroot conga line in the middle of the table. That way if they charge you you are most likely going to have the entirety of your firewarriors use overwatch, not to mention draw additional fire and force intervening model cover saves.
Anyone think this is utter suicide?
