Easily 10 nora overcosted if not 15... This is a rune that has gotten lost in transition with global formula based costing. It is sitting at 90 nora base for the upgrades it needs. It is simply well overcosted. This is a good example of wqhere changing its stas around simply won't help. It's kit includes the skywing beacon 1 time use ability, although very helpful, must be well over its due cost or something. This rune is just not worth the cost it currently has.
It only pays 50 nora for its stats. I wouldn't say that's overcosted. Could give it 3-4 range to make it cheaper.
