You could choose to have one profession either armor crafting or weapon crafting. You could have really rare exotic and legendary armor plans and weapon plans drop throughout the world. It would add a little color having multiple sets of armor that get you to max level. Edit: Please leave comments with feedback. Even if you vote no, you may have a better idea. Edit: Also, a special type of material could be added to the raid maps, like instead of just spirit bloom in vog, it could be something like ascendant spirit bloom thats required to make these craftable items... or enriched helium in crota raid.
