well im smithing 100+3, i would give it a 5/10 cause there are only a hand full of synths worth it. smithing need more stuff.
not much t1 synths, hauby and hauberk, and then? maybe some pieces of drk or sam jse.

and there are no t0 synths wich you can try to hq. of course cursed hauberk is worth it but if you craft 10 of it you gotta wait a long time till you sell it.
the other items of cursed gear sucks. we need something like dusk gloves, hard to hq but at least you can sell the nq

or t1 synths like cerberus mantle that is worth to hq.
