Quite honestly, my biggest complaint about it isn’t even the fact that it’s abused (it is and we all know it). How do you role-play a person killing themself in front of you? It has become so commonplace that it is just ignored. If you really feel the need to do the suicide/shortcut thing go find a secluded place where no other characters have to witness and ignore it. People killing themselves for no apparent reason in front of 12 other people at a mine would probably be cause for the mine to shut down for the day do to the excitement, it would not be ignored.
I think its kind of funny that the suicide rate in Yliakum is greater than its population.
