[What is the actual item/mechanic/thing being targeted?]
all rocket launching items
[What would you like specifically changed about it?]
Block them
[Why do you feel that this change is needed?]
Due to an exploit to award XP by killing your own character with no effort
[Anything else you would like to note]
If the server gets updated to 1.4.4, unblock the rocket launchers because then you cannot harm yourself with them.
Only block if the exploit cannot be resolved with an other method.
