The quantity and quality of content don’t matter if the interface through with you interact with the content is terrible. WoD had far better class design, and as a result I enjoyed WoD far more than anything since.
Legion destroyed classes and classes have felt terrible since. At least fury warrior got victory rush back in BfA, and BfA’s enrage mechanic is better than Legion’s; those two changes have made fury warrior playable for me, unlike during Legion.
