remember normal modes are for people to have fun. Its not about grinding loot. That is what the hard modes are for. And for everyone who gets 4/5 drops in one night, there are some that still get 0. Just chalk it up to you got extremely lucky and enjoy your fortune. If you really dislike it that much, DE your epics, and try again.
Well, lets hope this game can make it the long haul with people like you, pushing that mentality around.
