I don't know, maybe I'm wrong here but the grenades just feel . . . right . . . to me. Looking at this as a game and not a simulation, in very simplistic terms, I can shoot a long way. I can only throw a grenade a short way. It makes for some interesting choices. If I see some targets grouped, can I get to decent cover and toss a grenade at them? I'd like to capture one or two . . . can I get close enough to toss a stun grenade without putting my soldier in danger? I kind of like the way it works right now (19.6HF2).
I agree that I don't use grenades all that often but I always carry a few . . . you never know when you might need 'em.
