_ Light brawler with good speed and 2xAMS for missile protection. There is only half ton of ammo because you are expected to not attract LRM attention, so it do the heavy "protection" against streaks and ATMs.
2 AMS with only a half ton of ammo between them?? I came up with something similar, lacking in firepower compared to pulse lasers, but set up to offer lots of dual AMS support: _
Yes, because AMS are mostly useful as a quick burst damage denial rather than used in any prolonged fight or to protect allies. Unless you are looking to counter any missile above ATM optimal range, I see little to no point to fit more ammo: at almost point blank range AMS won't protect you against most missiles, and thanks to your speed you should be able to either run away or close the gap in little to no time.
Yeah, I never build AMS support to counter short-range missiles. If that happens, I consider it a bonus. When I make builds involving more than one AMS, it's to generally chip away at the overall missile traffic in the air during all stages of the game. This Javelin build I'd use to generally stay around the big guys to provide firepower support, hit open components, and provide a moderate umbrella.
