the current frag grenade is nice, but its not very useful
the actual Explosion is weak/very small radius, and the sharpnel is very weak and doesnt do much damage
the only kills i ever had with a frag is when i hold it too much and it kills me
when i played in general trench warfare, me and my team mates were throwing lot of Frag grenades to a trench, and the frag barely hurted the enemy
So im suggesting a stronge frag grenade:
More sharpnel, or stronger sharpnel, or both
Stronger Explosive damage
Text timer for the fuse(maybe a RTB Pref)
Faster sharpnel, goes farther in closed areas
HE Grenade:
The HE grenade is effective and much stronger, but its not very reallistic because the explosion ignores walls
since its not normally possible to make it detect walls and bricks
how about, it shoots invisible(or partially visible), similar to the frag, and in contact with bricks, they do an explosion from the back of the projectile .
