I think that striker is fine the way it is (except melee range should get a buff to match the hunter) Defender however should get buffed. The shield should activate on hit, not on kill, the bubble should not be able to be burst by nova bomb, razors edge should not be able to travel through it, or do any damage to it. And if Golden Gun is to pop it it should require every single shot. Also suppressor grenades should be fixed.
