I tend to agree with you that charming is a set avaliable to everyone
in Avalon (thanks to loremasters). I would LOVE to see magic items and
spells limited to only those with alchemy or charming. We tried that
for a short while with just pentacle items and the whole of Avalon
accused us of trying to ruin the game.
Take some comfort, however, in the knowledge that most professions have
a skillset or two that those professionals deem to be underpowered or
worthless.
