It's an unwritten law. Just because the rules don't specifically state it (yet) doesn't mean it isn't cheating.
You're engaging in unfair competition, on purpose.
You have a splendid reputation Mablak, and the respect of the whole community. But this makes you really no better than say... Zippo.
Unwritten laws are pointless in a league, we can't reasonably expect players to abide by them. Especially not new players, who would have no idea about such things.
BnG is an excellent example of how unwritten laws have gone wrong. Everyone has their own strange idea about what 'cheapness' entails. Some Brazillian once told me that you can't attempt the same type of shot twice in a row (though for him it was fine to do exact repeats every
other shot), and some people now cry foul if you teleport near the middle of the map, even if you're a legal distance away.
Expecting people to follow unwritten laws has caused endless drama in BnG, because people are essentially playing with different sets of rules. I would say that encouraging the creation of unwritten laws is the source of much of the unfair competition in worms.
