I'm thinking about starting a Tau army. I love the rail weapons, I love how a lot of the Tau models look... but not really the crisis suits. Which is a bit awkward, since that's their signature unit and seems to be what competitive armies are based around, even after the points hike. But with the new points I don't feel *quite* as bad trying to build an army without crisis suits.
Patrol Detachment (T'au Sept):
HQ:
205 (-2 CP) Coldstar Commander w/High-output burst cannon, 2x Plasma, 1x Fusion, Stimm, 2x Shield Drone, Precision of the Hunter, Vectored Manoeuvring Thrusters
170 Longstrike w/2x Seeker missile
Troops:
80 Strike Team
Fast Attack:
105 Pathfinders w/3x Rail Rifle
105 Pathfinders w/3x Rail Rifle
Heavy Support:
145 Hammerhead
190 2x Broadside w/Heavy Rail, Twin Plasma
Total: 1000, 1CP
Lots of railguns! Probably too many. If that's possible

. 2x Hammerhead Railgun, 2x Broadside Heavy Rail Rifle, 6x Pathfinder Rail Rifle. Plus several plasma rifles between the Broadsides and commander, and a decent amount of pulse/burst weapons scattered around.
The commander has a hilarious amount of movement. She should be pretty much immune to melee with her 16" flying dodge every time someone tries to charge her, but I worry that she's still not especially tough to shooting and could get caught out if she tries to get too adventurous on her own.
I'm also concerned about the pathfinders dying easily to... everything. No one even has to get close to them; bolter fire will mop them up. There doesn't really seem to be any way to help them out defensively via stratagems,
HQ abilities, etc. I like everything the unit can do for offense, utility, and mobility, but does the weak defense doom them? Does anyone have experience using them?
Also, any advice on Tau in general is welcome; this is (I think) an unconventional list and I also don't have experience playing them, so I may be making some big mistakes.
