You never jump to blink / boost away from melee enemies that sneak up on you?

It’s not like you /never/ jump and sometimes Grounded’s bonus damage against you applies erratically. It’s definitely not the worst modifier, but it’s not super duper friendly.

This week’s nightfall was relatively easy and kinda fun, too.

Yes, because that’s how I normally beat my nightfall strikes, by jumping around erratically. Seriously, how does one write such nonsense? There’s no reason to jump about, at ANY point during combat within the nightfall. Grounded is an utterly arbitrary modifier.
