Hey you guys thanks!
-NPC nerf, I would actually be against this as rune production will eventually outproduce current npcs, espically when it comes to crafting multiple runes & imbued runes.
-overproduction of high level runes, I would like to state that runecrafting will be introducing larger amounts of higher level runes. That is the purpose of rc is to reward working skilling players. of course it would take you awhile to level, we're not talking about getting 60 rc in one day. With a larger production of runes equals a stable "runes" economy. right now to be considered a mage you have to pay for all your supplies which isn't an ideal play style.
*May I remind you guys that these runes are a depleting resource, once you cast a spell they are gone. So with larger amounts of higher level runes being produced = more mages = more rune consumption = more demand = stable prices overall
I'm not exactly convinced with your theory because I don't honestly believe the price of runes prohibits people from using magic. In other words, I don't think magic use will increase in response to the increase of runes. Instead, I just think the server will be flooded with runes and the prices will crash, which is shitty because its called rune-scape for a reason.
In any case, I would be happy to take part in trying to properly balance the skill with some calculations. I have comprehensive data on the collective magic xp gained by the server as a whole from which I could estimate the rune production by NPCs. We could introduce the skill with the intention of replacing this production rate with runecrafting and then nerfing the monster drops. If admin decides to add this skill and you'd like my help, don't hesitate to message me.
