WoW is played by millions of different people, who have different ways of having fun. Some like levelling, others like Raiding, Battlegrounds, Arenas, Pet Battles, or Mount Collecting.
I myself am no exception to this and like most of the above, but there were also other times where I had tons of fun. Some of my most pleasureable Experiences came when I flooded the Auction House with cheap goods, because I had Excess Cloth stacks after Tailoring Levelling or wanted to get rid of Shoulder Enchants Stacks that were amassed as a side product of making Gold via Vendorin Soulbound ShoiulderEnchants.
To me, it was hilarious to read angry Rants of complaining competitors whose Gold incomes suddenly plummeted. I was mesmerised by streams of mails and Chat queries of them trying to persuade me to to put higher Prize Tags, and desperate wannabe-AHBarons who saw me putting hundreds of cheap Items on the AH yet again after they bought out thousands before in an attempt to raise prizes.
And it's not even like I was selling less than Mats cost or anything, I just made a handful of Gold profit per Item (which amounts to some thousand Gold per Hour) as opposed to the other Sellers who expect to do some clicks and make hundreds of Golds per each Item.
So yeah, do any of you MMO Champions have Ideas which Items, Item Types, and//or Markets to crash in order to generate Internet Tears, to have AH People feeding me with their Anger?
