Dark Knigh needs some changes

That said, they could reduce the base HP while increasing mitigation while the barrier is active. In that way the damage required to break it goes unchanged (same total eHP) but it will have a lingering effect against the excess damage of the attack that pops it.

Small buff that could be nonetheless worthwhile against very large hits.

25% barrier HP = 25% eHP.
20% barrier HP + 20% mit while active = 20/.8 eHP = 25% eHP (but with reduced impact from overbreak damage).
