a nice one Hiir
Just wanna add, we crafter usually willing to craft for free, especially trivial matter like repair or single meld
Some of us even compete (those with secret agenda lol) to help melding others gear
all you have to do is ask nicely

as for HQ craft, we do expecting you to bring all HQ mats, though we gladly accept the challenge as long as you understand the consequences. we do inform you (back in 1.0, havent try craft in 2.0) when we attempting to go for HQ, telling you the odds, and let you make the final decision

again, all you have to do is ask nicely
