Barrier knights are the [i]only[/i] barrier champions in the game, at least since I picked back up Destiny 2 in season 15, that cannot take crit damage while their barrier is up.
It's not really an issue if you're running the powerhouse build that is prismatic titan right now, but if I want to relax and just pluck away with my anti-barrier scout, it is infinitely frustrating.
Please tell me I'm not the only person who's noticed this and is annoyed by it.
Edit for clarification:
All other barrier champions (Colossus, servitor, and hobgoblin) can currently be critted through their barriers.
