While it was uncommon, that wouldn’t defy expectation for me post-buff pre-Lootpocalypse though, which is why I’m thinking that it didn’t actually change anything. Personally, I get the feeling that it didn’t do anything to the drop rate. I’m not entirely sure about it, but I actually think that a lot of the people talking about incredibly loot luck are people that either didn’t do much PvE before the event or hadn’t played much since the legendary drop buff.
My friend and I, who played copious amounts of PvE after the loot buff, have all agreed that there’s been pretty much no noticeable difference in the legendary drop rate. At best, the chance of getting the “rare” legendaries is better now than it used to be (before the event, there was, at least for all of us, a huge bais for 1 legendary from each boss rather than an exceptional chance for any legendary).
