I had an attempt at it, got interrupted because Ortega decided to go for her in Hide and crit her for nearly all of her remaining 2/3rds of HP, but initial impressions are not-good-not-bad.
>Red Sand Snipers on challenge mode crit for around 1300 at full HP, which drops rapidly with Safety First
>without being in Overcharge, Red Sand Rangers do 20-30ish damage to her in critical HP
>Sweepers still rape her like they do to most janky Berserker builds
Her damage is still pending investigation. Her full HP crit at long range with no Frenzy stacks on a Red Sand Sniper was around 2200 damage from still stance, which is kinda depressing, but I did build her to a very specific set of parameters (close range, Frenzy, low HP) so it's not super surprising
