My Suggestions (again) Are more weapons :
2nd : Radio Commands (For people without mic for mumble)
3rd: The Blocks Underneath the entities are unbreakable (i've seen my Brother troll people by Destroying Blocks underneath Spawn points)
4th : The CP (Control Point) , Please make the CP not walkable , People hide their to Camp me ME ME
5th : Can CAN you Add Parachute or Something like you have like 5x5 white blocks falling on your head while you fall/Spawn Falling.
6th: The Right Click of the Spade , will you make it to kill people (+10 Damage)
7th : Fix this Glitch : While i was Digging underground with my Spade and left click , other blocks won't destroy!.
8th: when you get shot the world view of the player model will get some blood on their clothes.
Thanks thats all ^^
