They don't even have to release new adventure packs. Things like the release of Spirits of the Lost back in t5 was fun, and it gave a bunch of end-game guilds something new to do, and everyone, including those who did not raid, were able to quest for the froglok race, etc. Just little things to keep our interest while they actually come up with something good.

It'd be cool if they provided players with in-game tools to create their own instances and quests. I'm pretty sure they could cook up some loot algorithm to drop some randomized loot or pick out existing items.
