I have some suggestions regarding Revenant's QoL. I think that there could be changes made to specific skills in order to feel more smooth. So, let's go straight into it:
Forced Engagement - this change aims for the smoother skill usage when swapping Legends.
Call to Anguish
Weapon Skill (Shortbow): Spiritcrush
Weapon Skill (Off-hand Sword): Deathstrike
Trait (Renegade): Sudden Reversal
Well, I think these could be useful without making major changes to the skills.
