Looked up Runecrafting and that is exactly what I wanted! Thanks! Starting to lvl it now...
A few tips from a 300 Runecrafter.
1. Find a friend you can trust and use him for your mat source. Butchering and Mining go well with Runecrafting if you can give them to someone to craft into green for you to Runebreak.
2. Your most precious resources while leveling will be kinetics and sentience, of all tiers. You will get a lot of uncommon dust/shard/crystal while breaking, and very few recipes use perpetuals. Any recipe that uses only uncommon mats is gold for leveling. Running out of kinetics and sentience will be your bottlenecks. You can transmute one of the three into another, but it costs uncommon mats and some gold.
3. Runecrafting has an odd leveling curve. The journey from 140-150 will be more mat intensive than 150-160 for example. Don't get discouraged when you see your mat per skillup costs suddenly jump, because they often fall back down soon after.
4. It's equally bad to over level your runecrafting as it is any other gathering skill, but far easier to do. It's going to become problematic if you don't have a high enough skill to break down the greens you are receiving. My advice would be to take a break from questing and start mat grinding. This works well if you are a butcher because you can mobs for gold and experience while you gather hides and cloth to give to a outfitter to make you greens.
