We do like to change things up and have something different occasionally, and if you want the previous gears, go to the Fairy Auction, it's up for grabs there.
And the reward is not just the end of quest, from there is a reward that can benefit all.
If you go to the Charity NPC and choose the "What's in it for me" option and give it a read, you will notice that the prizes are gained at the end of the fund-raising, and that there is a exp rate change in the 100mil tier.
I wonder if there are others at higher tiers.
I'm also starting to wonder just how many times I need to explain this.
Or if anyone even reads what NPC's say...
