Godlike
Caineghis (10) vs Naesala (10): Not sure on this but I think this works. Honestly I'm starting to feel like Dhyer's 'calculate damage based on % of enemies doubled and factor % of enemies doubling into durability' method may make the most sense for FE.
Ashera (10) vs Athos (7): Rar Ashera eat puny Godlike FEs.
Heavy
Roy (6) vs Ephraim (8)
Eirika (8) vs Elincia (10): Elincia doesn't have the stats for this, also a general thumbing of nose at authority stars.
Middle
Colm (8) vs Oswin (7): Oswin only needs a >33% chance to win via damage to Colm's >66% via ID.
Micaiah (10) vs Oscar (9): Colm losing means Micaiah takes Middle.
Light
Gilliam (8) vs Sanaki (10)
Soren (9) vs Volug (10): Eh.
