I have a 3 changes that will hopefully put an end to Luci-spamming, for better or for worse.
1. 20 damage per ammo, not 25.
2. Increased knock-back, and proportional to damage dealt.
3. Overcharge uses 15 ammo now, and hurts like getting shot in the chest with 300 damage. And watch out for that splash damage.
This will end secondary fire dretch insta-kills, primary fire Adv Dragoon insta-kills, and will take 2 full shots to kill a Tyrant, if he has full health and doesn't regenerate
Although these changes might not make it better, it will make it different.
