Thanks folks, this is quite useful.
To be clear, I'm trying to put together a list of approximately 20-30 fighters for Inner Sphere, and 20-30 for Clan, that cover a range of sizes and roles (small & fast, big & slow, somewhere in the middle) for the era 3025 to 3075. Each ASF can be assigned to multiple factions (up to 3) or be generic across the IS/Clans, but I'm trying to make sure the faction assignments make sense. My factions are:
Inner Sphere:
5 major houses
Comstar
WoB
Rasalhague (can piggyback off Steiner/Kurita ASFs)
St Ives (can piggyback off Davion/Liao)
Wolf's Dragoons (might be hard to find Dragoons-only ASFs)
Clans:
Wolf, Jade Falcon, Ghost Bear, Smoke Jaguar
Steel Viper, Nova Cat, Diamond Shark
Star Adder, Wolf-in-Exile, Hell's Horses
I also don't want to get into a situation where the main IS factions only get shitty 3025-tech ASFs and not some of the later ones.
So getting a sense of what's common in each faction is definitely what I'm looking for.
