The crafting system is not quite what I expected either, and is really rather quite a disappointment. I'd hoped we'd be able to upgrade any armour we liked, rather like an advanced system of the 'armour enhancements' from Assassins of Kings. I think I would still prefer a return to that style of system, with expanded possibilities. (The Glyphs are virtually worthless, as far as I'm concerned.) In such a system, one could upgrade a very low-level armour (say the Warrior Jacket, or a brigandine, if one liked) to rival much better harnesses, by adding a variety of enhancements. Examples of these enhancements could be: pauldrons (shoulders), gorget (neck and throat), besagews (upper breast and armpits), cowters (elbows), tassets (groin and upper thighs), poleyns (knees), greaves (shins), etc. These armour additions could come at a high price, which would give us something to do with all our tens of thousands of Crowns, and could be limited by the 'slots' or upgrade-potential of each armour. To make even more of a challenge, we might need to find these attachments for the armours, or have them specially crafted. There could even be different levels of enhancements, like before: magical, rare, epic, each with different bonuses. I believe the upgraded Witcher Gear is intended as a similar idea, but it seems to lack versatility, and is thus rather static.
So far, I've only crafted one or two armours, and a couple swords, which I out-leveled quickly. Otherwise, I have found all the equipment I'm currently using, and it's all much better than aught I can craft at my level (26). I have lots of diagrams, but I hardly use any of them. And, since almost all my promising diagrams require level 30 - 40, what good are they?! The system could have been handled differently, and I'd really have liked more control over the customisation of gear. A bit too late, now, sadly.
