"You already have crabs, so it's not bad if you get herpes also!" is a horrible way to argue your point. Two wrongs don't magically make one right.
Not just that, they're also very "unspecific" and uninteractive. If raiding is the only thing you do then sure it's a non issue. As most of the time you get teleported by your raid either way or you have a flight point close by. But then the whole bullshit about interacting with the world more danger and blablabla that has been used to justify and cited as reason for their removal to begin with falls apart.
It's nice to see that a lot of people have long since dropped that and now merely go with "there's no reason why you'd need that anyway" which is a horrific reason for removing anything. Might aswell remove 95% of WoW for that same logic. Who needs Shadowmoon Valley in BC for example? Why have two starting zones in Wotlk? Why have summoning stones when warlocks can do the same? Might aswell remove all these things because "Why not?".
