Nah, I mean true glass jaw luck. I recall one fight in which my lance, Marauder, Warhammer, Hatchetman and Vindicator, were advancing towards what was to be a messy three sided fight. First shots at my lance had rounds fired at both the Marauder and Warhammer. An enemy Blackjack hit the Marauder in the head with an AC2, knocking it out. The pilot then failed to regain consciousness for five rounds and when he did he immediately took a PPC to the head from a Battlemaster and died.
In another case I had a Warhammer in a close quarters fight with a Marauder, got an average hit on it with my SRM6, four missiles hit. Head, Center Torso (Critical), Head, Center Torso (Critical).
I know it was just RNG, but we just had the things go down way too easy too often.
