The thing is, they even made that not enjoyable anymore. Legion mog running was a godly time for mog and mount runs. I had 168% movespeed on my paladin, on top of bear tartare which made that like 220% so it became not only efficient, but I actually started timing my runs to challenge myself to see how much faster I could get during them. I was essentially speed running molten core on my paladin in under 6 minutes and could have definitely gotten to about 5 minutes if I brought goblin gliders. (before they nerfed them in raids)
People complain that the move speed sets were too imba in pvp and maybe so if I was bursting very low leveled geared people but it was an extremely unoptimal build and wouldn't stand a chance against anyone even in normal gear vs me being mythic geared. So they nerfed the move sets, you can only get +3% more movespeed from azerite, and they nerfed bear tartare from like 70% to 8% and completely killed one of the last things I truly enjoyed farming in this game.
