What the hell is wrong with crafting?

[tymora]

Preserve saved so many of my synths I lost count.
For success, I now use Preserve, Fulfillment, Maker's Muse, Ingenuity, Assembly for all crafts (because I am lazy to change the actions often).

With the above, or a subset depending on crafting level, I get about 50% success on +10 recipes with adv. support, all required manuals and using the correct craftmanship type.

I can usually skill-up on +8 rank recipes with the above setup at about 75% success rate or so.
