Then 2 minutes later, a brown Wizard Hat drops... but it was the pointy 58 Gandalf Hat that you know is trash before you even ID.
Luck was on my side this morning! Sometimes I do wonder if the actual % is tweaked (not the RNG but the drop %)... as they never disclosed that number for legendaries; they did say they doubled it for 1.0.5, but again, never disclose the actual rate.
The day before Thanksgiving I got a whopping 21 browns/greens (MP2/Maxed out MF)... it certainly felt like someone bumped up the % rate, but I was probably just immensely lucky that day. Never saw anything even close to that # of drops again.
