do you guys not have alts?
what have you been doing all of SOD?
most people realized in phase 3 and 4 that dumping their unplayed altâs professions in favor of turning them into mooncloth/refined salt/cured hide/essence of air+water+arcanite bar printers was the proper way to start the lvl 60 content.
most people also realized that scarabs and idols would occasionally flip/skyrocket in price as far less people would go to AQ once nax came out.
the smartest of people realized that T3 gear required mooncloth, arcanite, cured rugged hides and arcane crystals to redeem, so they bought it all cheap and made absolute bank this phase.
to be honest, idols skyrocket and then dip low all the time. just wait for them to dip again then purchase what you need.
on my server, the only scarab that is consistently expensive is the gold scarab.
the prices are what people make them, and what has happened to gold scarabs could happen to every other scarab if someone is willing to rinse the AH and take on the risk of ending up with a bunch of them they canât sell high.
considering i.e clay scarabs are like 30 silver atm and there is only 200ish of them on AH, i would not be surprised if these skyrocket to 20-30g+ soon.
people will buy and bite the bullet.
this is why you have flippers on AH, because it works.
of course there is the risk of some Andy coming along to post another 50 stacks of 10x of the type of scarab you were planning to scalp, and when this happens you are forced to either buy them all out at a relatively high price (say 2-3g per scarab), or give up on the endeavor and accept the loss because you donât know if he is sitting on 500 more.
however, if you are an AH Andy that frequently look at the prices, you will quickly get an idea how many of each type that is available in total, and thus be able to relatively accurately gauge whether or not someone is sitting on those hypothetical extra 500 scarabs and thus avoid getting screwed by a âbuy my
or post lowerâ âblackmailersâ.
its called a âlockâ among the pro AH nerds.
in any case, the only way to get around having to deal with this, is keep a solid stock of various items that you got for cheap, ready for use in case you need them.
or simply have a bunch of alts you can use to craft 10-20 of each material every 3 daysâŚ
for example, right now, Pristine Black Diamonds are in the literal silvers and there are so many of them, but if these are needed next phase for tier gear or whatever, they will skyrocket in price, so if you buy just a few stacks now and just speculate, you might be able to make 200x the amount you invested in them⌠if not, well, you didnât lose that much gold anyways⌠try again 
miners are also eating good this phase.
arcane crystals are making people who are willing to go farm ore nodes a giga fortune.
