Hi. We all know it, yet no one does anything about it. So let me explain, even though we are all aware of it.
So, my squad is happily in green cover, a bit clumped, it's a tiny wall, but all is dandy so far. Then, a grenade comes in, all over the wall, and guess what: the grenade drops down exactly behind the wall. Really? Grenade went through the wall? How? We never see nade bounce off wall. Nor we see a red zone saying nade will bounce off wall. No, we just see nades passing through walls happily. Wiping squads. Entire squads. Why entire squads? Because they are clumped together. And you can't control individual squad members.
1) nades passing through objects
2) clumping in cover
Someone do something about it please, quickly, it's becoming reeeeeeeeeeeeeeeeally annoying!
