HoW was the best era because there was so much end game content. Both raids were relevant because you wanted elemental burn weapons for POE. Trials was fresh and it also had elemental primary rewards. POE was worth playing because it dropped etheric light. IB also had good rewards and etheric light. It basically took TDB and added a ton of content to it. Nightfall also dropped good rewards and xp boost. TTK released a raid and made the other 2 obsolete. It made POE obsolete. It made all your weapons/gear obsolete. Court of Oryx which was hyped beyond belief was a total flop. The dreadnaught was also mega hyped and it's a total flop. Nightfall was made irrelevant. How released great new pop content with trials ... tsk added rift which is a flop. One of the only major positives from TTK was the new subclasses.
