Q u o t e:
First this is not a QQ post about the drop rates and such and what needs to be fixed.
One person, or even a minority of people not getting a drop is not, necessarily, a problem.
For myself, I will submit the following evidence:
5 80s capable of doing the event, 5 non-80s capable of getting drops.
ALL of my characters except one bank toon got squashlings. 4 of the non-80s through trick or treating.
All of my 80s got the achievement (though the ones I wanted to get it on took about 1 week longer to get it than the ones I didn't care about).
My one plate wearer finally got the plate laughing helm on the very last day of the event. For her, it had NEVER dropped while I was playing her. This character and others saw multiple plate helms drop in the same batch of runs, sometimes.
During the course of my trick or treating, I used the Innkeeper NPC, 2-3 times a day, for about a week. After that, I didn't trick or treat at all. During that time, each character got at least 2 drops of toothpicks during that week x 3 per day.
The only truly rare thing was the mount, which I saw once.
Of my 5 characters that could run the HH, I only did it daily on 2. The others saw the HH about once every 3 days. So that was a total of 40 character days worth of runs, x 5 runs per character (for the 5 characters in the group).
Less than 20% of the runs had NO rare drops other than broomsticks.
About 10% of the runs had multiple things drop at the same time. Once there was even a squashling, cloth helm, AND sword.
On average, 2 items dropped per character run set (5 runs).
All of my characters, even the ones I was not running often, had their achievement by the 10th day. One character got his achievement on the last day, but that was because of me not doing the GNERD Rage or Candy grabbing till the last day with that last 80. He had the squashling, toothpick, and the cloth helm well before the 10th day.
All in all, the drop rate seemed decent. One had to commit to about an hour a day per character to get a group, trick or treat, and kill the HH 5 times.
It really appeared as though nothing was wrong.
Sure I would have liked to have had more mount drops, and I heard many people say they got it on their alt, but such is life.
If I wanted to complain about drop rates, I would %#**! about ToC dropping Caster Mail when I finally brought my plate tank in :D
