SE ended this thread today.

They added a ~6500 dps check to Faust in A1. So tanks bring STR accessories.

Then they added a 25,000 damage tank buster to the actual boss. So tanks bring your VIT/Hybrids.

VIT onry tanks and STR onry tanks aren't ready for Savage. Players with both sets plus Hybrids are. (from a gear perspective)
