Warrior subclass themes: raging about rage

As I was looking over the skills all 2nd job warriors will be getting I found myself questioning Rage. I'm now wondering why fighters are getting this skill. Under the assumption that we will get 3rd and 4th job progression similar to OSMS, rage makes no sense for fighters.

Rage now lowers ones def for an att boost. This theme of sacrificing something for power is eventually a DK theme not a Hero theme. Spearmen get no unique att boosts in 2nd job, they get the defensive skills HB and iron will yet they can't use shields. Isn't page>WK>paladin supposed to be the supportive tank? Why are paladins threatening enemies? Shouldn't pages get iron will to lean into the tank theme? I feel like fighters should be the ones using threaten as Crusaders are the ones inducing panic and shouting at enemies.

Unless Nexon is cooking big time with 3rd and 4th job none of the warriors 2nd jobs align with their 3rd and 4th job themes. Thematically spearmen should get Rage/power guard (sacrifice survivability for power), pages should get HB and iron will (support tank) and fighters should get threaten and power guard (CC and status ailments).
