I made a suggestion on redmine for "cower" and "hide" skills for crafters. Similar to /sneak and /smoke except that the crafter cannot move from their current location without breaking the effect...
That's certainly not a bad idea, it's not overpowered yet still useful for crafters.
I've upgraded to mason already so I have plenty of more options, however I still feel bad for crafters trying to level, people who are into minecraft for the main purpose of the game - To build. They have no defense for when some jerk wants to come into their house and start griefing away until they strike chests full of items. For non-donor's especially who may be new to the server and find themselves overwhelmed by the number of people after their stuff with no way to defend themselves.
The problem I just described however isn't going to be cured with a simple hide and seek type of ability, perhaps there's a way to hide chests instead, effectively making their chests look like glass or something and who breaks glass while raiding? Not I, it takes too much time to go get some sand and make more glass so I stay away from that and regular stone (although if I know a town has stuff hiding behind stone I take regular stone with me to undo any griefing done)
Anyway it seems perfectly logical to be able to disguise a chest as a crafter, right? I mean they are craftmen after all, if they can make a chest out of wood they should be able to make it out of other materials, don't you think?
