I like the update. Imho, edgeville looks a lot better than before. I'm very happy they improved it as that is where I spend most of my time. It looks more...townish now.
About the shops, I really don't have much to say about them, but it's a good update. Don't listen to Arab about the runes, he's ignorant . I didn't look at the rune prices but I highly doubt that it will affect rcers much. It's easy to buy mass quantities of runes off players, doesn't take long at all.
Btw, any guide we have with a shop picture in it will have to be updated, however many that may be.
