Still not getting what the issue is here.
No one has reported being unable to get someone meld for them and many crafters will meld for free or be happy if offered a tip.

I get that some people just don't want to have to talk to other players, even though this is an MMO, but even they have an option. All they have to do is level their crafters to 60. As somebody pointed out, you can do it through leves and buy the turn ins, you don't even have to craft!

I don't think it's reasonable to ask for a major change in the game just to suit a few people who absolutely refuse to interact with others or put in any work.
