Id be down with it, if Krabs did what you mentioned earlier. If you make cannonballs, they take the same amount of time as osrs.
How I came to the conclusion that it could hurt the game is that as an ironman ive had over 1b cash with nothing to do with it. Items like the cannonball at 4k each creates a pretty good sink of cash for the server. People think cash sinks should be giant cash values but having lots of small cash sinks such as cannonballs or making unf potions included with the larger cash sinks such as the Well.
