Besides, a Spartan should be able to chuck a grenade like a baseball. As for grenade spamming in multiplayer, it's not that bad as long as they aren't infinite. Plasmas are terrible against infantry unless you can stick them, and the frags require precise timing to nab a vehicle. The only people who bemoan grenades in my experience are those who whore vehicles...

Also, I too think they should add gore in Halo: Reach. If this is going to be their most realistic one yet, let's not skimp on the details.
