Since the last Iron Banner event (July 28 to August 4), Iron Banner attunement doesn’t seem to be working correctly. In fact, it almost feels like it’s doing the opposite. I attuned a the Felwinter's Lie weapon, but over the course of more than 50 matches, I only received it twice. During the previous Iron Banner, I received my attuned weapon about three out of every four drops, so the difference is significant. It seems like something changed with the attunement system. I hope this issue can be investigated and fixed before the next Iron Banner event.
