The next update in Ragnarok Online’s Classic server will bring the Transcendent classes, improvements to existing classes, which can be unlocked upon reaching the maximum level.
“Classic server is now ready to launch War of Emperum, over the course of three test WoEs we have opened up all of the realms and castles, as well as the guild dungeons,” says Producer Jason “Heimdallr” Koerperich, Ragnarok Online Producer at Gravity Interactive. "With the launch of full WoE castle holding guilds will be able to invest in a castles economy, improve its defenses, pick up treasure, and access the guild dungeon!”

I think they shouldn’t update the RO classic much. That or nerf the renewal server. Renewal server feels like a nerfed private server IMO.
