I do believe that this is a great update! Exited to find out how the new features at barbarian are. Also great to have an extra slot for the wings..
I do hope that the economy benefits from the changes made to staking, it would be really nice if the Grand Exchange will finally be more useful. But, I do think a lot of items will simply drop in price.. Take for example items like bgs, zgs or dragon claws i dont think there is a lot of demand for these. From now on people will start selling these weapons a lot and my guess is that the price will lower a lot, too.
Those new EP items look great! Really wanna try those
