Junk, Phara, Bastion could probably break any double shield comp at that rank.  Moira's Ult always surprise low health Orisa or Rein hiding behind shield.  I recently discovered that it's also useful VS a good Sym since her and her team mostly feel safe behind her ult and Moira's ult go through it.
