At current, the greater loremaster feat Artisan gives access to craft race/class restricted items and about 12 crafting points for craft completion only.
For charactera interested in crafting that has no class restrictions (like alchemy), this isn't a very attractive feat. I suggest instead of just crafting points, the feat should give craft skill points players can allocate into forging or tailoring or any other skill.
At current, the formula would give around 12 total crafting points for most loremasters with a chance of giving 15 for loremasters that also take skill focus: craft mastery and epic skill focus: craft mastery along with the e/sf: lore feats. I don't think that would upset the crafting world, but would make the greater knowledge a lot more attractive to crafters.
