Spells: Spell Resist changes

[Lownstar]

I am not sure if this is the right place to post but since the patch i have noticed mobs are resisting spells at a much higher rate. a 44 shaman in COM casting malisement 3 times in a row gets resisted on a blue mob(goo and a greater plaguebone). Root (when it lands) lasts for a few seconds, even if malisement landed first. Not sure if this was intentional but there is a noticeable difference after patch
