Personally I think double jump should be baseline for everyone, but rogue is a good start. For me it's mostly a QoL issue, on my DH I can navigate almost any shitty terrain blizz wants to throw at me with just double jump, an occasional glide here and there. I mean apparently grappling hook is becoming baseline for rogues (unless I misread that and it's still pirate one, and I'll admit I've never used as I haven't touched the former combat at all this expac), so it helps based on what I've seen, but still...it's not double jump. Even SS can't really be as useful as double jump for navigating since it's dependent on a mob you can target.
Agree it would be cool, but ultimately homogenization that makes the game less fun overall. Should Demon Hunters get stealth? Cloak of Shadows? Shadowstep? I say let them have their cool thing so that we can keep all of ours.
