Warrior Rework Idea

But how necessary is a stun specifically?

Especially when I've made Interject work against all interruptible skills (Be they ability or spells).

Stun stops an enemy for 5 seconds from attacking you at all.

Well, it's not that necessary, but it becomes handy for example in Eureka when you fight against mutatet monsters 5 levels above you with the wrong element in defense...
Leviathan Ex, the add wich casts fear. Stun it right when it spawns and you have 5 seconds more to burst it down.
Stun the last boss in Qarn Hm when a party member is tethered, so the boss can't run after him and he doesn't turn into a mummy.

A stun is not only an interruption, but also a mitigation tool.
