Of course the mount isn't the only thing to be had -- there are plenty of other goodies dropped by the scourge of Sleepy Hollow. I'm going to be running some alts through and pick up the Ring of Ghoulish Glee on a few of them. The nice combination of attack power, crit, and hit makes it a solid choice for nearly every beginning level 80 melee DPS.
And while my warrior has been sporting the level 70 helm for three years now, he's going to have to go back and get the updated level 80 one. Gotta' collect them all.
I think this is one of the holidays that the loot from the boss overshadows the achievements and the holiday themselves. Perhaps it's just because this was the first real holiday boss we had that dropped enough special stuff everyone had to farm it as much as possible, or perhaps it's just because the mount is so cool. But nonetheless, the achievements are all there too waiting to be completed.
For more information on the holiday, check out our Over Achiever Guide to the Hallow's End Achievement, and the list of the level 80 Headless Horseman rewards.
How much do you plan on farming the Headless Horseman? Every day on every alt possible? Or just a bit?
