I can just use the Scouting toys on any of my alts, which unlocks every flightpath in every expansion in history.
Being faster and efficient to travel between raids, battle pets, etc would be utilizing a combination of Flightpaths, portals in SW/Org to get as close to your destination choice as possible than using Soar would.
Even before the reduction to the cooldown that was made in phase 5, it’s still a very niche ability in terms of travelling vast distances efficiently. You need to have verticality in order to travel vast distances. If you’re in a zone like the Dustwallow Marsh for Onyxia’s lair, you’re gonna have a hard time finding a tall area to leap from. Sure, hop on a flying mount, fly to Thousand Needles, but that isn’t fast or efficient.
I can literally give probably about 2-3 more examples that would be faster than using the Soar ability in terms of traversing old world content as or more efficiently, but I don’t really need to get into it because most people already know how to do it.
If you feel that it legitimately is detrimental to the experience, then by all means, have your opinion, I’ll just make sure to list things like this to Blizzard as counter-arguments.
As I’ve said many other times before though, if they decide not to change it, it’s not game breaking or going to ruin the expansion, but it still makes the ability much less fun to use, so people should feel free to express that if they feel that way.
