I’ve noticed a shortage in certain items, like lower-level gear or food in the G.E. I do understand that a player-driven economy is the focus and very important, however in certain cases the supply does definitely not meet the demand.
Also there seems to be a difference in the value of GP per item. 15M for a bandos chestplate is in my opinion a very fair price, but i personally cba to spend 500K on a single Saradomin Brew Flask, paying approx. 83K per portion.
IMO the price of certain supplies necessary for skilling or PVMing could be more regulated, giving starting or ‘poorer’ players the chance to dive into certain content without having to spend days grinding money-making methods.
I also agree with @Iron Tyrone that low-level bosses seem to be quite hard in comparison. Using T90/80 gear i’m personally not able to proficiently do GWD1, due to the high hits, resulting in the use of more (expensive) consumables and reducing the chance of making a profit, relying purely on rare drops for profit.
Keep in mind i’ve only been playing for 2-3 weeks, so i might not have a complete picture of the economy or the game.
