I love the anniversary buff, but my luck has been a little more tempered. I found a nice [url="http://us.battle.net/d3/en/item/the-butchers-sickle"]Butcher's Sickle[/url] that sold for a decent amount, but everything else I've found was salvaged. I'd like to craft something with additional pick up radius and not lose any other stats, but I haven't been that lucky yet.
I'll pass along the feedback about using buffs for special events, and feel free to keep posting your thoughts on the anniversary buff.
What about a 25% MF/GF/Exp bonus for 15-30 minutes if you clear every single boss in an act (let the bonus stack over to the next act.
For instance, if I play A1 through all of the bosses, I have a bonus similar to the anniversary boost for 15 minutes, or 30 minutes, or a random time between 5 mins and 30 mins. This boost would start at the beginning of A2.
