It's simple. Current Shinra should have AE Type 1
The Evangelist is the literal embodiment of the collective unconscious and despair itself, while Shinra's mom is the evangelist's opposite/doppelganger, representing Hope. Shinra later fuses with both his brother and mom (Hope), becoming Hope itself. This should give him AE Type 1.
I agree that this would give Shinra AE, however Oblivion didn't explain why it's Type 1 AE, Oblivion didn't give any scan or reason why it's Type 1.
