Hey all,
I don't know if this is deliberate or not but Sedna's Pounce ability doesn't interrupt teleportation. Also, I've rarely seen it interrupt any other spells or abilities, but that's likely because they all cast pretty fast and it's hard to time.
I think Pounce should interrupt teleportation, as it has a "cast time" and thus interruption is implied by the description of the ability.
