"probably the TOP thing the designers and I are focused on is barriers..."

I’m actually more of a fan of the other two options.

  1. MainTank Orisa, OffTank Sigma
  2. MainTank Orisa, MainTank Sigma, weaken at close range selfpeel
  3. A modified 1-3-2 with offtanks being moved to DPS, but maximum 1 offtank per team. Then buff barrier tanks till popular enough
