Of course it had restrictions, and they were reasonable restrictions! At a Terran Battlefleet level I needed one minimum Tier 1, one minimum Tier 2 and two minimum Tier 3 squads to have a legal build. In the sample fleet I listed above I had that, Tier 1 = Battlecruiser Squadron, Tier 2 = Torpedo Cruiser and Destroyer squadrons, Tier 3 = a Missionary and two Wayfarer squads, all legal by the current build rules.
Now lets look at the Helix model. Now I admit I have no clue how Warcradle is going to set it up, but if you use Firestorm Planetfall's setup, as it is, as a basis it might look something like this.
Terran NTSC helix build (using the V2.0 factions as an example)
Core Helix: Battleship, 1 to 2 Cruiser squads, 1 to 2 frigate squads (assuming a basic starter/patrol box of a Terran Apollo battleship, Teuton cruisers, and Armsman frigates) with the 6 helix slots looking like this...
Heavy Helix: Heavy Cruisers, Gunships
Carrier Helix : Carriers, Heavy Carriers, Assault Carriers, (and maybe Battle-Carriers?)
Battle Helix: Battleships, Dreadnoughts, Battle Cruisers, Battle Stations, (and maybe Battle Carriers could be here instead?)
Cruiser Helix: Regular, Assault, Torpedo, and other alternate cruisers.
Frigate Helix: All the varieties of Frigates and Corvettes as well as Light Cruisers.
Support Helix: Destroyers, Defense Platforms, Space Stations, Escort Carriers, R&D Cruisers (although one could argue that R&D ships should go into the Cruiser Helix)
So with the Helix setup being that you must take a Core helix and then build around that, would kinda make that above fleet build impossible, and it would limit your build variety. Being that no matter what I'd have to take a core of the Apollo/Teuton/Armsman squadrons, eating up points I might want to spend on other things. Like right now I don't use Terran Battleships in my fleet builds (the Tyrant is a POS and the Apollo isn't my playstyle). So I'll take a carrier or a single battle cruiser as a my Admirals vessel and take a Hawker battleship as my front line combat ship. Helix system puts a crimp on that.
But I will admit, I don't know exactly how Warcradle is going to implement the Helix system, they may come up with ways around this and make it better, I don't know . But the preliminary idea of it though, I'm not keen on .
