Why do you prefer Classic over Retail?

Current retail leaves me feeling unfulfilled all the time. Now that I have lvl 120, unlocked alliance race, and lvl 30 neck power, what is left for me to do? Go do the same Mythic + again for a chance at a TF?

Vanilla I could set goals for my character. Farm X piece of gear and then move on to the next. That just isn't an option today, you have to sit and wait until Blizzard decides its OK and you can move to the next level of gear. ( Look at Emissary quests awarding higher level Azerite gear, based on the players current ILVL). Timegating is not a solution to me, more real content is.
