You will get more rares in the same amount of total farming time from farming an act worth of elites and bosses, from start to finish, than you would have from boss runs in the previous incarnation.
total amount of farming time? No way. That's my whole point - the drops are now nerfed to the point where it's not rewarding or fun whatsoever. I was LOOKING FORWARD to being able to play acts 1 and 2 and get some decent loot. I still have friends that are playing those acts. Don't get me wrong, I am ALL FOR more loot!
This patch IS NOT more loot. Lol.
It was seriously better before. I would rather grind for months in able to get to act 3 and actually loot good items and have a fun and rewarding experience playing. Now it's like regardless of which act you're playing, the loot is a bunch of garbage.
Before, it was kind of like a scratch off lottery ticket... you win some, you lose some. They're really good at keeping you hooked, coming back for more.
Now, it's like playing the damn powerball. You throw a dollar at it every once in a while, but there's really no hope in ever winning.
