Some good ideas TRC. There's a change or two to the list that I have in my proposal(that I'm hoping will get posted soon). Actually I don't mind the move of Crisis suits to Support and the price of additional Devilfish for Pathfinders included in their costing. I like the Barracuda squadron design of 2-3 - it's nicely done. I like the bomber, 4+ armour for the Sharks too. I don't mind the adjustment to the Hero tracer numbers. I quite like the inclusion of the turrets and the hammerhead variants in the list. It makes sense. I don't mind the change to pack size etc. purchasing. I don't mind the adjustment of the special rules - it is a smart reduction while keeping them in the list.
However..
Fire Warriors don't need 4 different options. You can already do pretty much everything you outline for them in the current list design. Why change it? It's just added lines on a page. Also, 18 mechanised FW teams + transport?!! holy crap that is a ridiculously large formation. It's way too unwieldy. That's 27 units for just 675 points! Even the walking FW formation = 17 units! I'm hoping I misread this design...
Crisis Suits. You ask if there are too many weapons? Just because you believe that the number of suits per base doesnt take into account the number of weapons - it's all abstract! You might have a mix of weapons in the formation. As usual, it's forgotten that Epic is abstract

And still no MW FF? that
still makes no sense for a weapon that is MW - will crisis suits hold fire with the fusion guns in an assault?

Geez!
Broadsides - do we really need to be told "solid shot" railguns?
Heavy Drones - do we really need these? There's no model. They seem superfluous. I can't find any in the GW range either. Do they actually exist? Why not just have standard drones with MLs?
Hammerhead (RG) - 4+ to hit and a speed drop? I agree with Onyx. If you implement this you better drop the price mate. 375 for a formation that has been pretty much found to be,
over time with playtesting, priced correctly is a bit steep if you then gut the unit. I agree with Scarik on this, I think they should stay 3+. They need to be the hard hitters the Tau are supposed to have. If the artificial 5+ assault value remains then they need to be scary shooters at least. I can live withthe speed drop somewhat.
Sentry Turret - you might want to add Fearless to them if you want people to take them in this incarnation. NOt sure if expendable is a replacement for this....
Deflector shield - I did have a big rant on this until i saw the DC 10 change. I'm not sure about a 5+ inv save basically. I'll reserve judgement on this I think. Not sure people wil be happy about the gun ranges on this baby. E&C jumps to mind here for some strange reason

105cm? Why not just 100?
Support craft - oh man! what is the problem with adjusting this rule?! Is it sooo difficult to say it still adheres to LOS rules in the MRB in regards to 10cm-in rule? Good grief!
A-X-1-0 - 30cm Rail gun shot? Eldar aircraft pulse lasers have a 45cm shot. Why make the Railgun any less ranged? You've removed the Moray - the Tau cheaper version TK platform. I can understand focussing the aircraft into the TK support. But why force a short range on a long range weapon - one that out ranges pulse lasers on the ground?
All in all, some stuff needs adjusting while other stuff is good. It's a decent list if the changes needed get made.
