It can be solved by requiring players to return their money to the RS gold game and getting rid of the circulating currency. While I'm not sure about the Araxxor issue, I believe it's an excellent idea to offer incentives to players to spend their money in a way that does not go to another player.
As a relatively inactive player I do not have the knowledge to suggest reasonable ways to get rid of cash. There are a variety of methods to dispose of money that have been around for years like shops, sawmills and so on. They controlled inflation pretty well from 2001-2009.
However there's no way to make it enough. It might be possible to adjust the prices and selections of shops to ensure there's more spending similar to actual stores. Maybe the amount of gold sucked up by monsters needs to be reduced to a lesser level than it might already be. Maybe I'm not right however the rate of inflation, which is exponential by nature seems to be driving things worse, while one's rate of acquiring GP, is not.
What are your men's most cherished achievements from games? It was something which made you feel great when you finished. It could be anything you like, including the level, comp cape, killing an employee, or even doing something in your community. My 99 Defense would probably be my own. It had long been on my wish list due to the importance of defense when the tanking process. Since 2006, I have not had any members so I had no choice other than to play it in freeplay. This was obviously murder. I also got it during my inactive stretch between 2007 and 2013.
In the summer, I would play for 1.5-2 hours a day to get 50k defense experience. Even though it was only for a short period, it was very difficult to get into the game to obtain that experience. I wasn't even keen on the game at that moment.
The reintroduction in 2011 of wilderness and, most importantly, the removal of Revenants from a dungeon was what saved me. Since the spot was never used by players, I could AFK Ice Warriors there for the 50k xp per day.
It took me a while however, as I was unable to force myself to log in for more than 2 hours, even AFK. I finally got my chance in 2012 and I was glad to be done with it. In the same time, just after I achieved 99 Defense EOC was released and killed clanning, so I have had a hard time tanking with buy OSRS gold my 99 defense. I did tank once, in a fun war against Sals Realm as well as an additional clan. At that point, I was at the 98 defense level.
