I think this is a bug. When I switch into archon the sheet dps does not change. I am at ~108k and with Archon it should be over 140k but it does not change, and yet when a buff like BBV is applied my dps goes up to near 170k, which is way more than BBV should be giving.

The buff to armor and resists shows up in archon form, just not the dps. If it is an error, it is a display error as damge certainly increases in archon form
