@Sassafras I completely understand your concern. There are numerous reasons why this is being prioritized, and it does not mean that those other updates are not being worked on, just that this one is also being worked on. We have multiple developers, I've been primarily working on this update for a few weeks while Chad works on server related updates (such as the ones you've mentioned), and another developer is working on fixing up RuneLite bugs that arise. We also wanted to wrap up the client updates with this piece of content that we think really sets us apart from other RSPS, there are no others that offer HD + 2010 style graphics + RuneLite simultaneously. Nonetheless, we are still working on server updates simultaneously :)
@Extremedanny OSRS areas (eg. the Zulrah map and boss) will look exactly how the do on Alora right now. The only difference is your character / items will look different in that area.
