:Jet packs would shoot you up into the air 6-7 blocks high,
:Armories would give you ammunition and allow you to change weapons. I know it was suggested for the tent, don't go ballistic.
:Bangalore torpedoes would allow you to drop them and crouch to avoid damage from the blast. Can still team kill griefers that are using it.
:No griefers or trolls!
:Concussion throws players away a little if they're to close to the grenade, disorient them. Post what you think, and as always, the golden rule, Be excellent, not annoying.EDIT: FYI Bangalore torpedoes were used in WW2 on D-Day(the one that comes to mind) as well as other times during the war. Their use was for destroying the enemies obstacles. They would fire the igniter, then drop to the ground to avoid being killed by the blast.
