You'd fly to Ruuan Weald and WOW Classic TBC Gold then walk right down until Gruul in Blade's Edge. It is possible to fly to Cosmowrench from Netherstorm. I am not sure, but I feel like the flight paths would be important again if there weren't flying mounts.

If Blizzard made WoW today, it wouldn't be referred to as WoW. It would most likely be an Overwatch MMO or something completely different. They haven't really made any progress with Warcraft in a long time (besides hearthstone which is a completely different thing).

If we contrast Overwatch with what could have been , it's Project Titan and WoW and what might have happened if WoW were released in buy WOW TBC Classic Gold 2021. I believe WoW2021 would be constricted to some half-assed BGs along with some Arenas, and some loot boxes.
