Quick question about Hawk's Eye

[Bardo]

Well, positional accuracy definitely applies to Bard as well.

It seems that maybe spells are all considered to be omni-directional though, so they always count as hitting from behind?
That would make sense as to why their accuracy caps have always been calculated to be lower than physical damage caps.

None of my mages are 50 or I would certainly test it.
But if it's true that spells are omni-directional, then you're definitely right that Hawk's eye is pretty much worthless for BLM/SMN.
