Commander 2x Fusion Gun, Puretide engram chip, Eridium Armor
2x Shield Drones
To run with the other Crisis Suits, yes? I've got two things to say here: (1) If you're shooting 8 Fusion Blasters at something, do you really need the Puretide Engram? I suppose it gives you some flexibility, but it isn't going to be doing as much as it would, say, with a pack of Missile Pods. Also, (2) with the exception of Imperial Knights and the odd Wraithknight, when do you need to shoot something with 8 Fusion Blasters? I'd try to throw some Target locks on the Crisis Suits just for the sake of flexibility.
Riptide with Ion Accelerator, TLSM, EWO
Love it. No advice. Optimal build, in my opinion.
3x Crisis Suits with 2x Fusion guns each. Shas'vre upgrade. Shield drone
See above for most of my comments here. The other one is to ditch the Shas'vre in favor of some Target Locks.
Drone squad with 7x Marker Drones
Two squads of 5 pathfinders
17 Markerlights is too many. I would ditch at *least* one of those teams of pathfinders in exchange for more guns of some kind somewhere. Frankly I think the marker drones should be sufficient.
Stormsurge with TL Airburst Frag Launcher, Pulse driver cannon, Shield, EWO
This should make your enemies sad. Good work.
2x 10 Kroot
10 Fire Warriors with Devilfish and Shas'ui
Kroot without Sniper Rounds are Kroot wasted. As for the Firewarriors, I'd recommend the Disruption Pod for their Fish--keeps them alive longer, get them where they're going. With the inclusion of the Shas'ui, I infer you plan on using this unit to take an objective and hold it? If such is the case, consider Pulse Carbines instead of Rifles. Pinning doesn't *usually* work, but the days of everything causing pinning to everything is gone and you might surprise somebody. In any case, if they're running upfield to take some midfield objective, the Pulse Rifle range isn't strictly needed.
Optimized Stealth Cadre
2x Stealth Battlesuits. Shas've with Fusion Gun and Target Lock/Marker Light
Ghostkeel with TL fusion and Fusion Collider
I assume those are teams of 3 Stealths apiece, yes?
I love this formation, but I don't like the Fusion that much. If you're looking to take out vehicles, the Ion Raker is all you need in most instances--you're pumping bullets up their tailpipes with the Wall of Mirrors thing, so the Melta ability you can do without and the extra shots are much nicer. Keep the Fusion Blasters on the Ghostkeel, sure, but ditch them everywhere else.
Also: dump the Markerlights on the Shas'vre (you have way too many markerlights already) and dump the Shas'vre altogether. With the points saved from all of that you can buy yourself another stealth suit or, if you'd prefer, a gun drone for each unit. Use the savings from the Fusion Blasters to get Drone Controllers and you've added to your offensive output.
Overall I think you're spending too much on toys in this list and not enough on actual guns and bodies. It isn't a bad list by any means, but you could trim some fat.
