For the rest of the skills in Enforcer, I just balanced it out with the Hitman concept.
- Basic: While 3 or more enemies within 18 meters are targeting you, you receive a 15% damage bonus that lasts for 7 seconds.
- Ace: While 3 or more enemies within 18 meters are targeting you, you also receive a 15% damage reduction that lasts for 7 seconds. Does not apply to melee damage, throwables, grenade launchers, and rocket launchers.
Anyway, if you want, feel free to leave your thoughts in the comments below.
