Conjuration perk: Bound weapons will cast soul trap on a target.
Enchanting perk: Death blows to creatures trap souls for weapon recharge.
Talk about redundancy. Not only do these perks do the same 'base' thing, but Enchanting is clearly vastly superior. Now, it may just be an issue of recording. Neither of these perk trees have been officially released so it is easy to imagine that there are differences (outside of one working ONLY for X, and the other for everything) that have not been noted down. But if this is an accurate description of the perks, why the clear overlapping?
It may also be the case that the actual in game effects are different, despite the description. Maybe the Enchanting perk does not apply to bound weapons, or maybe the Conjuration perk soul taps for a long duration letting you trap with spell-kills. Duno. Anyway, what is your thoughts about a) potential overlap of perks B) clearly superior perk in the overlapping situations c) possible reasons why there is no overlapping.
