Blockland isn't supposed to be realistic.
Or we would have legs,btw I bet you have the blood and gore mod enabled so it can be more realistic.
I do not have the blood and gore mod, for your info.
And to prove my point about it being cheap, I got a 15 killstreak while camping with RC Sapper on Nobots DM server the other day. I don't care about realism, if I did I would say some crap like that the guy has to hold a remote after deploying the Sapper. I just care because it's cheap.
Anyways, I edited the script a week ago to make it one time use. Unfortunately I am not sure how to remove the Sapper from the player inventory after use, which remains the problem.
