These are the settings by default for competitive:
Code:
ff_damage_reduction_bullets                        0.33
ff_damage_reduction_grenade                        0.85
ff_damage_reduction_grenade_self                   1
ff_damage_reduction_other                          0.4

So how about these settings:

ff_damage_reduction_bullets 0.33
ff_damage_reduction_grenade 1.0
ff_damage_reduction_grenade_self 1.0
ff_damage_reduction_other 0.4

I have made the above settings default now.
