That feel when you start up Crucible, stick a guy for first blood, stick a second guy for second blood, and proceed to clear up the rest of the softened enemies with a few bursts from your Monte Carlo... absolutely delicious. Without a high discipline / grenade regeneration build though you're not going to hit the double grenade mark most of the time in PvP or PvE if you find yourself using your grenade regularly, though I still feel there's a ton of utility in having your second grenade start to recharge if you need to sit on your first.
