I've been using ninja since he came out, but I just started noticing a couple weeks ago that he's missing attacks ALL THE TIME, even when the hero he's attacking doesn't have any dodge (war chief, for instance). There was no mystic or panda or any other hero on the other team who could have placed a negative accuracy debuff on him, but he missed 4 attacks in a row on 70 war chief (who has no dodge).
Was there a balance change that I missed that made ninja have reduced accuracy to the point where he can miss against any hero? Have any other ninja users noticed it?
