I've noticed something strange in MegaMek, and I'm wondering if anyone else has, and if so, which rulebook I can reference for an explanation:
Starting a dropship out at Altitude 0 reduces the BV of the dropship by 30-40%. It's not a set percentage, and I'm guessing it's a re-calculation of the dropship construction rules.
For example, I want my players to defend a Union dropship during a campaign mission, so I've been testing it in MegaMek. The 2708 version has a BV of 3962, but when I change the starting altitude to 0, the BV drops to 2651. For the 3055 Union, it drops from 4977 to 3098. Any ideas?
