If we're going with raising EXP for craft levels, as an attempt to be helpful I would suggest 1% total EXP required for level-up per the item's skill level, or 3 * the craft's skill level, whichever is higher. Something like that should be guaranteed to scale reasonably well at all levels. I would still like for us to have traits for improving crafts, however, so taking the bonuses suggested and making traits out of them would be nice (even though I agree with Chaos in the regard that the Science trait needs a serious buff. Something like adding +1 to the received materials on successful non-raremetal rolls sounds good to me).
