Tech is now balanced by ships as it seems.
This pretty much means you can use [for example!] an Odin with Natterturms on a Molly ID at 90% (normally it would be 90% Ship * 90% Guns = 81% Core), but if you try to use Trefoils or Sammaels, which would be at 100% for Molly ID, it puts you at 10% core, because the ship('s faction ID?) doesn't "support them at 90%". I think Flashpoints would work at 90% as well though.
Hm...question is what nerf what ship gets though, does it go by ID right now? For example a Lhotse on ALG ID, could it use TEW guns at 90% overall core because IMG ID can use them?...
No idea. I just know that the nerf is currently calculated by two things:
Nerf for the ship and equip.
Nerf for if the equip doesn't match the ship.
Because I can use my Molly Odin with Hessian guns just fine at 90% instead of 81%, while I can't use the Odin with Trefoils or Sammaels, which would be expected as 90%, but ends up as 10%. As I said before...
But, ... I don't know what exactly the nerfs are for which ship with what equip.
The plugin checks first to see if your equipment works with your ship. If it doesn't, you get nerfed to 10%. This makes sense in-RP -- the BHG isn't going to make weapons that can be fit properly on Rogue ships, for example.
Then, if that check passes, it applies the technerf 100%/90%/75%/10%/1% thing.
Something tells me either the check is wrong (unlikely) or no one ever posted the new techcompat_ships chart (more likely).
