So the unleashed Amon changes you're looking at come from the March 19 update.
Shamash, Nephthys, Vishnu, Sati, Zephyrus, and awakened Tyr (not base Tyr) also got changes to various degrees.
Awakened Tyr's changes included a big thing; I mentioned them in the general thread a few pages back, I think.

Huh, Vishnu's page doesn't list the changes she got. Ok, so her burst's side effect used to be a cumulative def debuff. Now it has been replaced with giving herself a barrier. That's actually a buff considering her passive...
Which used to include wiping all buffs on her when she takes damage. But that part got changed to wiping out the self-buffs from her 1st and 2nd skills upon taking damage.
