These two defeated Ragnaros thanks to their resistance to fire, so I'm wondering if they can defeat Archimonde at their prime? We know that Titans are vulnerable to Fel, but we don't know if the same applies to their creatures (they have an arcana inside them, but not as much as Titans) and Odyn and Tyr have Light magic, so the possibility they have an advantage ? Thoughts?
P.S. Also don't forget that the Titan Keepers lost most of their power after the war with the Old Gods. It was written in the Chronicles that during the battle with C'thraxxi in Tirisfal Forest, Tyr was left with only a shadow of his original power.
