Sion's Soul Furnace Ignoring Snares/Stuns.

I would like to point out that Sion's new Soul Furnace is ignoring snares and stuns by other champions, specifically Veigar and Morgana and even ignoring some push backs. The ability is supposed to protect him from damage not make him completely immune to snares. If that was the case then Morgana's shield should be able to ignore snares too. Just like to know if this was intentional or not.
