I noticed that in the story, "Chaos Theory", which comes in the Alpha Strike boxed set, Star Colonel Aren of Jade Falcon is piloting a Warhawk...in 3151. However, in 3151, the MUL says that Jade Falcon did not use Warhawks (they seem to be the sole domain of The Scorpion Empire).
Is faction availability on MUL intended to be a balancing aid? If so, is fiction ignored? Or are the MUL's faction lists for thematic purposes, and not for game balance?
I played a lot of Alpha Strike the first time it was released, but then a player in our group started building very abusive lists (i.e. spamming rare units) which turned the rest of us off. He was eventually ejected from the group, but it still tainted the game we had at first very much enjoyed. Now I'm playing a lot of it again, and teaching a bunch of "new to BattleTech" people, so I want to avoid the same thing happening again. Not sure if the MUL is part of the solution or not, or if it's just up to pre-game negotiation and "gut feel" to create a balanced game (realizing of course that BT has so many units that balance will never be perfect, or even close to perfect).
