So what is the concluded "ideal" range?
Someone mentioned that items within 10 levels of the area bonded at some absurd rate...

So lets say we use a crafted I70 as an example.
Would that be ideal to bind in an I60 dungeon (Pharos, Haukke Hard, Copperbell Hard), an I70 Dungeon (Lost City, Bray Hard, Hali Hard), or an I80 Dungeon (Hullbreaker, TTD Hard, Vigil Hard)?
