I like your crisis suit squad that double as your S7 profile and your
ML profile. Solid idea. Keep in mind though, that's a large footprint. You might have to play test it to see how it handles in combat, but the function is there.
In general, Tau are an ok shooty army, but markerlights make them great. Glad to see them in there. Just remember that riptides come with a markerlight tax, especially for the
IA profile. You have that covered.
You might be able to save points by dropping VT from one of the riptides. I feel that having two riptides with VT might be too much. That choice ultimately depends on your meta.
I like piranhas and would like to have more in my army (currently 0
lol). They are a decent melta platform that is quick and can hit enemy lines T2 in most cases.
I'm trying to think of problems this list can encounter. I don't see flyers being a big problem. You have a full crisis squad and commander shooting 16 rockets w/ PENchip + 2
IA riptides. You MIGHT have problems from hard to reach
AV if your piranhas can not get to them, but you still have two riptides. Hordes won't be a big deal because of riptide pie plates and plenty of
FWs.
" Otherwise the odds of destroying AV12 fliers aren't great. At least with the
FB on each you can make 2 no fly zones. "
If he Nova charges his
IA, he'll get a ordinance S9 AP2 large blast. That's stronk. What makes metla so good is it's attack at half range. I doubt a flyer will be within 8'' of a riptide.
"I think you either need to go in the direction of more maneuverability or more gun line. "
He has two DF, and that's a lot of maneuverability. I would maybe argue that another small
FW squad of 6 or 9 to hold on to at least one objective at home would be ideal. One or two DF is plenty of maneuverability. Outflanking kroot is meh. He already has one, and adding another won't ensure contesting any kind of objective mid-field or on the enemy objective simply because Kroot are poopy. 6+ armor save? :|
"If you aren't feeling the Piranhas you could get a suicide Bodyguard suit instead, with Fb x 2, Shield and Stim injector."
The loadout on those bodyguards is illegal . You can use 3 hard points on them. I assume you would want FBx2 and maybe the shield
gen. Let's look at point costs. It costs 174pts for the loadout you are suggesting (minus the Stim Injector since you only have 3 hardpoints.) That's pretty pricey. :( Keep in mind too, suicide suits should be made as cheap as possible with one goal in mind: To eliminate the target. They're survival is not suppose to be guaranteed, nor should it be extended by protective gear. Save those points for other equipment, those suits were dead the moment they touched down.
