Well i have seen the Carrier, and the singularity cannons (playing with neutrino now, and outfitting them with singularity cannons rocks ass). However beyond that I have to agree.
Based on having played with the hiigarans for about 10 times, and each times up to lvl 15 or so. And having played against them a few times as well (currently in a game where im lvl 22). ( I actually turfed them because i wanted to get a feel for the chance calc being used )
The following ships have decent spawn rates (in station):
- The Saari troop transport and anything below
- The Saarkin, Jneer, Vanaar and Skaal cruisers.
- Kuun-lan heavy missle cruiser
- Qwaar BC (obviously later in game, and it takes a while before you can afford it, but spawnrate is acceptable when used in combo with omnifactory)
- Koshiir BC (same as Qwaar)
- Taiid carrier (usually the first larger vessel the be available in station for some reason.)
The following ships are almost rare:
- Vihr freighter, its odd how this particular ship is almost never available. Which hurts the most early game. And i usually end up buying a freighter from an allied station.
- Sajuuk (never ever seen it)
- Hiigaran mining station (never seen it, is it even a flyable ship?)
- Wodaan carrier (never seen it)
- Neerin superfreighter (rare: but have seen it once or twice, i think its also used in the boarding fleets)
- Sajuuk khar (never seen it)
So you can get most ships in station as being the player. So that is not a huge issue. And coincidently its not my main concern.
What my main concern is is that i have never seen an hiigaran AI fleet fielding anything stronger then cruisers in their fleet. Not even when playing against them, in which they had like 7 stations spread over 2 systems. So thats why i thought that there might be something wrong in their faction file or something.
Its simply statistically impossible for them not to have such fleets when all the other factions do. However I am willing to do more testing.
edit: forgot to add: Rebel fleets do have fleets with BC's and stuff.
