For the new players panicking:
The squish only matters if you want to buy vendor items, like fast flying or the tundra mammoth, because vendor prices don't get halved. You have 2 weeks to get them if you want them. In the super-inflated prices before the gold squish, literally a few hours of good old grinding (e.g. gathering professions) will be more than enough. You can even get 5k easily by farming in low level, vanilla areas for a few hours. Keep in mind, that in this case, the squish comes in very very handy for you. After the squish, you'd have to farm twice as much for the vendor items or fast flying because you could only sell your things at the AH for 50% their current price.
For the players thinking it's not fair:
No matter what people will keep saying and crying about the squish each year under this topic, it'll not change the fact that it literally does nothing to the VALUE of things. Unless you want vendor items, the squish doesn't concern you. You want to buy a primo before the squish? It takes you around 10-20 minutes of mining and 800-900 gold. You want to buy a primo after the squish? It takes you around 10-20 minutes of mining and 400-500 gold. Whoa, wait a minute, the time and effort required didn't change??? How could this be?? Well, what everybody should understand that the VALUE of things and the prices at the AH will always come down to one single thing: How much effort and time it takes to get the desired item. If we took gold out of the picture and stayed with our example, let's say it takes 60-80 Mithril Bars to get a Primo. The gold is just the tool we use to make these trades easier, just like in real life with money. No matter what a Primo will cost, because the Mitrhil Bar's prices will always follow the general inflation and you'll be able to sell them for a higher price so you can get your primo for the same amount of Mitrhil Bars.
For the short-time panicked hoarders:
Stuffing the guild bank with primos or cardinal rubies before the squish and spending all your money on them will do nothing to avoid losing gold, but guess what, you might lose gold but you'll not lose value. So why do the extra step of hoarding?
I never hoard anything, of course I store valuables in my banks but not because of the squish and not for a short time only. Even if I have 1 million+ gold spread across my characters I still won't panic buy primos and I'll always stay liquid. Never lost any money this way, and sometimes even earned a little extra for doing nothing.
