House rule question: Grenades and delay

[jester]

One thing I have noticed. Players don't tent to use grenades, much like many troops in real life.

For me, for the most part, I used them more for a prop, this solves alot of the problems for a GM, because it allows you a device have the characters deal with a number of faceless nameless bad guys in one fell swoop. And again when dealing with badguy NPCs it saves rolling and control, and it can also save the PCs in a desperate moment as they are about to be overwhelmed by bad guys.
