actually, I think they should be buffed even more. just hear me out.
do you have any idea what a shrapnel grenade does? little less what they would do with the technology in halo? not only is there an explosion, but the metal shrapnel is like a shot gun of sharp metal bits, and if the halo shotgun is an instant kill, don’t ya think the frag would be a little stronger? that said, I think the shotgun should shoot much farther and have less spread, and be a two shot kill at point blank-short range.
back to the nade, and explosives in general, I think there should be a counter maneuver, one that if you hear a grenade, you have time to use it if you aren’t busy jumping around or whatever. You could duck and cover, reducing the damage of explosive blasts a good deal, but you would be just as vulnrable to gun fire and it’d take a second to get back up and fire, so it’d be the same as normal except you wouldn’t kill a whole room of guys, just one of em and severly hurt the rest. if a few people chucked grenades at someone though, it’d be lights out, despite how flat they are to the ground.
I think it’d be a good game mechanic for dealing with some of the power of explosive without underminding power weapons, since if you have a power weapon like the rocket launcher, not only does it hurt more than a grenade, but if they lived from your rocket by using duck and cover, you could finnish them with a grenade or another rocket. rockets could get more ammo, like 8 rounds instead of 6, and could focus more on anti-vehicle combat, one shot kills against non covered enemies, and two shots garanteed to kill. I don’t see how a rocket kills a spartan when a shrapnel grenade to the face doesn’t, so it’d make more sense this way too.
perhaps have 1 starting grenade, and a larger max grenade amount like the limit of 4 in odst. that way, holding more than 1 grenade at a time is a reward for getting kills on opponents who don’t use theirs. also, to counter buffed grenade spamming, make it so that pushing the “throw grenade” button simply pulls out the grenade, and then you have to throw it, increasing the delay between shooting and tossing grenades, making grenades more of a tactical choice rather than a last resort.
