If we actually had a weapon that granted insta-kills at close range when fired on the rear of the ship, we would effectively have the Disco version of the Spy from TF2.
We already have cloaks, and IFF's serve as disguises.
EDIT: Now that I think about it... Disco -does- have ships that serve as most classes for TF2.
Light Fighters - Scout
VHF's = Soldier
Bomber with Hellfire spam? = Pyro
Nuke Mine Spammer = Demoman
Battleships (big, slow, but hard hitting) = Heavy
PoB owners = Engineer
Repair Ships = Medic
Cap ship with mortars/razors/missile turrets? = Sniper
What I just described above = Spy
Wide awake in a world that sleeps, enduring thoughts, enduring scenes. The knowledge of what is yet to come.
From a time when all seems lost, from a dead man to a world, without restraint, unafraid and free.
Mostly retired Discovery member. May still visit from time to time.
