Corrupting set items

Shouldn’t we be able to actually make set’s item better with rune of corruption?
At this moment every single set item that gets corrupted breaks. Is it intended or is it just a bug? The only way set item doesn’t break is when you get max/lowest roll on corruption but you never get any additional affix to the item, unless it breaks…

Please let me know if it works how intended or it will get fixed soon :slight_smile:
