Concussive Shot is one of the things that makes Zaeed one of the best squadmates in combat; it's effective against biotic barriers, and since he gets Disruptor Ammo for shields and Inferno Grenade for armour, it makes Zaeed one of the few characters with powers that hit every type of protection. He makes a great pair with Garrus (who also gets good weapons and can nail every resistance).
