Wrath was still the best system, IMO. A week's worth of running random heroics would net you enough badges to get a full set of the previous tier raid gear. I was not a fan of the Wakening Essences and the RNG chance to get legendaries in Legion, the cost of the items was too high and WQs rewarded a paltry amount. Emissaries offering previous tier raid gear would be nice instead of scaling with your current ilvl. I also liked the Argus system with Veiled Argunite, that was primarily how I geared my alts after Unsullied items since I hate raiding.
