I don't think I'd be far off saying 30-40% of my deaths are from grenades. The grenade model right now is absurd.
Frag/stick grenades are effectively impact grenades, put the timer back on frags like other BF titles. This is worse than the RGO epidemic of BF4.
If I get killed by an impact fair enough but the fact I have such a small chance of surviving a drag/stick grenade because they act like a delayed impact grenade is stupid.
