When we update cache in the future yeah, definitely will add them.

With RS3 there's not really a lack of content for us to work with, we'll slowly be catching up. But in the future we'll be looking at Telos, Slayer Updates such as Sophanem Dungeon and that'd bring Menaphos and Soul Altar runecrafting and heaps of new skilling methods. Something I'd love is Uncharted Isles, however, that'd be a HUGE project.
There's so much to do, with our Dev team we can do it, but I don't think we'll ever have nothing to do ?
