"If this is so, then I assume it would be too hard to get rid of all of the main line recipes when view/searching. "
I am not exactly sure what is that you are asking...
in the 2nd tier the combines will go up to 60, there will be 3 levels of items:
for example in smithing, there will be
-refined dark ore - trivial at 40 (same as final items in Tier 1)
-bar of dark iron - trivial 50
-actual crafted item - trivial 60
I have allready finished puting in all of the recipes, so you interested, you can start with
http://www.thehiddenforest.org/item.php?id=49621progress from there, and you can see where is recipes can lead, and which items it interconnects with.
-There will be 24 crafted weapons (12 from each side of the SB faction war, so you can only get access to half of them, basing on which faction side you allied yourself with), about half smithing and half fletching skills
-8 final tailored items (4 different capes and mantle each)
-8 final jeweled augments (basically direct upgrade to previous tier augs) + 2 jeweled range items
And finally 3 final pieces of armor upgrades (chest, legs and arms) will require preparation of some TS materials to obtain them
With 3rd Tier (which will take place in Gunthak), dependency on crafting may become even more severe
