No support reason why:
Skilling supplies have a certain price but if all skillers get more money while skilling they have a bigger amount of money so they can buy by example buy rune bars for a higher price as now so only prices will rise...
It introduces a nice way of skillers being able to make a nice profit, instead of being forced to focus on one skill just to make your money you'd be able to train your favourite skills with somewhat a decent rate. Now caskets don't have to be supper common, in no way am I suggestions like 5 caskets per inventory. Hell no.
But the reason "Oh, a price may rise if more money comes into the game" .. confused me a little bit?
If prices rose because more GP is coming into the game, technically nothing has exactly changed.
Let's say you are buying mithril bars at 5K ea and making your money from selling raw mantas for 2.5k ea.
Because a new way of GP coming into the game was released these prices have gone up. Mithril bars are now at 10k ea and raw mantas are now at 5k ea.
Where would the difference be? You're still make exactly the same, apart from the numbers may be a little higher. But my example is some exaggerated change and I 205% doubt it'll rise doubles, although there will be some prices which may go up, but I couldn't see this being anything negative.
--- What if say, combat was to have another way of making a bit more money? Would you support that idea just because it's combat related and not skilling? What would be so bad about having another way of skilling making a bit of extra GP? Do you feel like as of right now, no other ways at all should be released for money making? Do you believe we should have money sinks before anymore GP is coming into the game?
-- As of right now you could just set-up an alt to afk some npcs to casket farm -- Caskets which would come from skilling would be harder / slower obtaining than it would be from combat. --
