Pretty accurate, if Smite was redesigned it could also be a much more versatile group support Blitz as an alternative to shield, so Psykers could go Gaze and still provide meaningful contribution in higher difficulties.
Smite would now:
Stagger distant Gunner groups for teammates to close the gap.
Stagger Bosses for teammates to revive downed players
With Empowered Psionics it would:
Debuff initial targets with 40% increased damage from all sources
Stagger Ogryns for the full duration of Electrocution (8s)
With Enfeeble it would:
Debuff enemies with Electrocution status effect, reducing their attack speed hy 25% and increasing weakspot damage they take by 15%
