Thanks for the move trngl.
supersurprise, I will now quickly shoot down your idea in the nicest possible way.
a) Too much lag
b) Too overpowered
c) C4 can be used like this if fast at typing /d
d) Rockets or Grenades or Mortars can currently be used like this by firing at a wall.
e) Also, we don't need a 4th type of TNT (TNT, Big-TNT, Nuke and now this instant one? No thanks.)
f) Cherrybombs are pretty instant already, and to balance this we made it suicidable. Why would this be different?
g) Difficult to balance with the rest of the weapons in game.
...
z) I just don't like the idea.
