Grenade spam is the thing that ruins non-realism servers. How much fun is it when both sides are just sitting and chucking grenades at each other? You could try and rush out, but sooner or later one of those 'nads is gonna get 'ya.
The fact that realism servers limmit grenades means that face-to-face fire fights are alot more prominant.
