The same thing anyone else would do: nothing different.
If you have been using Auditor for any length of time, there is feature of it that is useless 99% of the time, but this happens to fall under the 1%: total audit. The release of 4.0 broke most of my addons beyond repair, so this is only since Cataclysm was released:
I broke the 400k mark for the first time a few days ago, but nearly 2 million gold has whipped through my bags in the last five months. Does that not count? Why do I say "I've broken the 400k mark for the first time?" And for that matter, what exactly is the value of the 400k when, by definition, for me to have 400k means that 400k of whatever net worth I actually own is languishing in my bags, getting no return?
Gold is primarily a way to keep score, for gold bloggers and many non-bloggers. If my gold total goes up from day-to-day, that means I'm
Thus I am skeptical of when bloggers like Mageshadow say:
I'm almost at 600k, what would I do with my million gold? Trading Card Game mounts for one, I've had my eye on a swift spectral tiger for a while, and a mottled drake & a riding turtle wouldn't hurt. I'd also probably buy a couple achievements/mounts that are obtained through raiding, mainly Invincible and Mimiron's head. I'd also probably hand out some gifts to my friends, mainly choppers and sandstone drakes.None of those things require 600k to purchase, so why wait? One million is a number. And actually, it is a pretty arbitrary number when you have already "handled" 1.8 million. If I had one million liquid gold I would get the Warcraft Econ interview and... nothing else. Maybe it does become easier in some peoples' minds to spend the gold when they have finally achieved their "goal," but I doubt that ever ends up being the case. Most people who make this much gold have made it because A) they have a hard time spending gold, and/or B) they are addicted to getting an ever-increasing high score. Spending 100k on a Spectral Tiger is indistinguishable from losing 100k on bad Glyph bet (or whatever) to such people. I especially think it's funny buying mounts when you can only use one mount at a time - you cannot ride Invincible, Mimiron's Head, the Riding Turtle, Sandstone Drake, and the Spectral Tiger at the same time.
Then again, maybe I'm just crazy.
P.S. Regarding those two epic weapons I got off Trade for 11k apiece...
P.P.S. I am still fairly confident that BoE epics will retain their value despite ZA/ZG coming out, simply because of the 346 ilevel requirement to zone in. The only sales you should be losing would be to the budget raiders who believe the 353 is good enough for them (and are willing to farm heroics), as compared to the 359 BoE. Odds are good that budget raiders weren't buying many epic BoEs anyway.
P.P.P.S. If ZA/ZG is faceroll out of the gate though, all bets are off.
