Hallow's End will finish soon, so I thought I'd run one of my alts around to get the buckets and see how much xp he would get.
Here are the results :
Vanilla - 1,870,330xp - 49 buckets
Outland - 572,550xp - 15 buckets
Northrend - 916,080xp - 24 buckets
Cata - 496,210xp - 13 buckets
Total = 3,855,170 = 101 Buckets
I may have missed some buckets, so there may be a few more about the place.
This is at level 85, with the 10% xp/rep buff, and each bucket gave 38,170xp.
This gives almost 30% of a level at 85.
Takes about 4 hours in total. But I did it in the background while catching up on other stuff.
