I have a guild friend who melds me all the time and nothing makes me feel worse than asking to get overmelds for my gathering class. I don't mind providing the materia or the 5-10% chance near the end, but what I do feel bad about is how much time of ours I'm taking up. It's gotten to the point where I'm better off buying the piece of gear I need overmelded and trading it to them and having them meld it multiple times with a single click.
