Epic Battles are currently unavailable on Anor and Ithil while we fix a bug. We will be working to correct this in the near future. In the meantime our new Storied Tales are available to progress through Helm"s Deep on the Legendary Worlds. A fix had been put in place for today's patch that had an unintended halo preventing some players from accessing Epic Battles, so we'll be re-doing that work for the next patch.
