Want to know why tank is almost always the role in need?

Sprint is part of my mitigation.

And so you should when your mitigations are most important, which is during trash pulls that output far more damage than most boss mechanics, right?

While I agree on some reservation with ARR content, and some specific dungeons like Amaurot with extra spicy pulls, wtw should be considered the bare minimum otherwise and thus it should be impossible for the party to pull ahead because you already pulled everything, and you should be using Sprint because letting it drift indefinitely until you reach the boss, which I must assume its what you mean because that's when you need to make snap decisions on dodging, would be a complete and utter waste, usually you can use it and have it back for the boss.

That said, if a Healer or DPS pulls ahead of you, does not bring it to you, and die, it's 100% on them and if they blame you, you tell them to hold that L, simple as that.
