I know your Idea, to protect the player, who got a gamebug and can´t play the game.
my suggestion: after a disconnect should the player defeatable for 30 seconds. Means If a player disconnect the game with alt+f4 any people can kill him at least 30 sec more.
the penalty for these guys: who killed in this time (disconnect+30 sec)=no C-Bills, no XP. Teamkill is teamkilll in this time. If a mech is destroyed, the player could disconnect without any penalty.
Reason: If the player disconnect, the other team didn´t earn the assist and the kill bonus.
