Question about leveling runecrafting on a max level toon
Okay so long story short: I'm coming back from a long break and want to get back into the game a bit. I used my level 60 boost on a mage but really want to play my cleric (healing on the mage is rough at their gear level). It seems stupid to not have max level runecrafting on the toon that's going to actively be running experts so I want to level it up on my cleric.
So my question is what's the quickest way to level runecrafting with no money? I spent it all before I left to get gear. I was thinking of leveling up armorsmithing and use the gear to fuel runecrafting but I don't know how feasible that will be or if it will be quick at all.
