Vanilla server, 1x rates, released without ZG/Diremaul and is the only private server to have pre-item revamp values and to go appropriately with the true timeline.
Had a few stress tests the other week and it ended up being really stable with over 2000 unique players online. It's been in closed beta for 4 years and is scheduled to release this upcoming 28th of Feb.
