Well to me it seems like the drop rate has been tweaked. For the better. Not so much about the Epics and the Legendarys, but I see more greens now. I think this is more like the way it ought to be. I had posted feedback before about drop rates and Hero types just did not feel right. Now that more greens are dropping seems much better.
PS Epics seem unchanged and Legendarys well maybe it’s been my luck couple of days, need more hours played to determine that.
