Another thread of similar forgotten content aka the Siege of Dragonbane Keep and its drop that is difficult to get.
Everlasting Horn of Lavaswimming
This is similar in fashion to Grand Hunts and content that was released with the start of the expansion already being forgotten about unless its the weekly for Aiding the Accord.
More needs to be done to make this content more appealing for people to want to do it atleast more than once a week.
