RuneScape DIY.

I would like the idea of partial DIY, meaning that you couldn't buy any kind of armour/weapons/ammunition from other players (maybe not from NPCs either, not sure of it). Hard to imagine how it could be done in practics but this would mean that if you want get good combat items you would have to work for them instead of buying them. Everything else could trade freely. This would mean that if you want a godsword you would have to actually get hilt yourself, If you want dragon hatchet you would have to kill Dagannoth kings to obtain it etc. And at lower levels if you want good armour you also need high skill levels to make them. You could still buy supplies for training, only combat related items would be untradable.
