I suggest the addition of a friend or foe system to certain weapons, since they debuff both the own team and the enemy team:
Energy-neutralizing missiles: They should only affect enemy ships. (Recon’s Slowing missile only affects enemy ships, too!!!)
Gravitational lens: The pull effect should only affect enemy ships. (Also: shorten the duration of it by 50% and reduce cooldown by 20% to compensate)
Slowing field missile: They should only affect enemy ships. (Recon’s Slowing missile only affects enemy ships, too!!!)
I never use these weapons just because they usually end up debuffing my team aswell and I’d like them to be of some use.
