Almost sure the increase doesnt affect Legendary drop rates. Did a couple dozen Bunker runs and got nothing. A whole buttload of purple and blue shields dropped in the arena but no Shams.
I was running Pete earlier. Dropped a Fabled Tortoise and another WTF, led me to "WTF?" since that's the 4th or 5th one in the last week. And this is excluding the jacked-up drop rates of "Orange Monday".
