Absolutely not! Don't turn this into a modern loot pinata game Blizzard.
It's so much much more rewarding finding a legendary when it's actually rare.
This isn't a game you rush through.
I mean.. there's a HUGE difference between Diablo 2 and Diablo 3 when it comes to drop rates. I'm not saying to make it like Diablo 3, but doing 1000 rune runs to not even get anything good wasn't that much fun. Rates should bit a little bit higher.
