This has nothing to do with his scaling and the added slow, but if I remember correctly, on-ability effects such as Glowing Wand and Magic Worship used to proc Gord's passive, which made Glowing Wand arguably his core item. But in the current patch 1.6.94, I tested it out and it doesn't proc his true damage anymore. Didn't it used to be able to do the former or did they just remove it? And is it an unintentional bug or an unlisted bug fix?
