Warrior Tanking

[Nalou]

Foresight, Featherfoot, Vengeance, Berserk are all (even in 2.0) proactive skills.

Yes, but defensively speaking they are (were) really weak. You don't pop Foresight to mitigate a table flip or a Spaceship crash.

How is managing Wrath not WAR's playstyle?

Well if you call this "managing" then it's probably better if we quit this discussion because we'll never agree.
