Truly, the worst of all vindicators. This double AC5 build will help you through its mastery phase. I assure you I have run this build on many mechs, and this vindicator has the cool down to pull this off. Alternative Ammo Build I personally average around 600 damage and 3 kills. That is when you will run out of ammo, and you're still pinging them with the mediums. If you have a cool down 5 module, that's an extra 12%, making it 42% cooldown. Almost like having 3.
