Major rebalance. I originally had the damage set at 65 so I could kill any player with two hits. Unfortunately, explosive damage drops severely with distance despite the high splash radius, so near misses harass a target but rarely kill it. Even with high accuracy and projectile speed (for an explosive weapon) the effective range was limited by a steep trajectory and a spread wide enough to make direct hits inconsistent at best and consistently unattainable at worst.

The weapon was only effective indoors, so I specialized it for that role. damage is increased to 100 (kills most classes with one hit), spread is increased to 190, projectile speed is reduced to 50, and splash radius is reduced to 4. It now has no long-range application whatsoever, but at least it's good for one thing instead of bad for two things.

This one's changed quite a bit from my original conception. I was trying to build a hand mortar, but I discovered that low grenade velocity stretched out the vertical dispersion longitudinally over the target area. I could sacrifice accuracy for velocity, but then I'd have greater horizontal dispersion; I could sacrifice ammo count, but then I wouldn't find my range before I ran out of rounds; or I could sacrifice power, but if the first hit isn't fatal, the enemy would probably recover before I could hit them again.

This seemed insurmountable, so I repurposed the weapon as a short-range grenade pistol for my CQC class. I had to make compromises all around, but it works very well on tight clusters of enemies and around corners. Block and vehicle damage is low, but the class I use it with has the Miner combat bonus, so I already have unlimited C4. Ammo is still low, but in CQC you won't get many chances anyway.
