I do not understand the whole unlocking old-school flight thing. We can fly anyway.
I think old-school flying should be renamed to hovering, and it should be given to mounts that don’t have wings, and be available immediately. Simple as that. And it just conforms to the terrain 40 yds up in the air but can go up and down anything and you will never incur fall damage. That’s what I’d do.
I am just sad for you that in TWW you’ll have to put up with it until you’ve got to 80 and done the campaign and explored everywhere. Do none of the new accessibility things help? They made extra speed ones this patch.
