Natures, iron, coal, sharks, yews, magic logs haven't increased the same percentage like whips, high end armour etc has.Not really. For every person who pays more for a raw material, someone else gets more for producing it.
It really isn't. For higher level players who make their money off monster drops the issue may seem smaller as their money making items have also inflated. But for the lower level community which uses raw materials, their prices have barely risen at all in comparison. The gap between the rich and poor has been greatly increased.
Things go up in price, and it also gets easier to make money.
The only areas really impacted are ones related to high alch prices and the like. Most of the rest of the impact of it is psychological, not real.
I started training runecrafting while it was the best option for money -by far-. (before the gwd I had it to 85, I stopped after the wilderness removal since I felt it made rcing another "repetitive" boring skill).
