The Escalation patch has introduced several new scenarios with respective heroic modes that provide shiny new loot. It is still too early to predict which of these will demand the highest prices at the auction house or AH, since it can take weeks for players to work through the content and determine the value of the new drops compared to the existing items. Many expect the rarest and most prized drops to start commanding handsome prices starting June, so just keep your eyes peeled for popular WTB requests in general chat and high-selling items at the AH.
WOTLK and Cata were my goblin training grounds as well (I remember fondly making 30k on a single day after a patch day with Inscription), but since Im only at Legion levels, Im struggling to find oportunities where to start invest and make profit. I've been carefully paying attention to the market and picking small batches of mats to flip. After 6 yrs out im slowly starting to pick up (so far i think i made 100k in a couple of months).
For what it's worth, I like the leveling changes, but I also think that the profession changes are beneficial. Once they removed the utility of most professions; it became more of a hobby. Crafting should be fun. When it gave perks, it was fun, but Blizz, correctly, decided that it was creating forced gameplay (min/maxers always picked certain profs). So they changed it. Well when a prof doesn't give you any gameplay perks AND it's tedious...it's not fun. Especially if you're starting from scratch and outleveling your profs because you're blowing through levels so quickly.
Disable alpha versions in your Curse client if you do not want multiple updates per day. Make sure you check main download preference as well as DBM's individual download preference. You could have primary method set to release and dbm still set to alpha. Right click on DBM itself in curse client addon list and set it to release/beta to avoid the daily updates.
Not improvements on audio, as expected. These are intended to make your speaker connections look more "professional" and easier to manage. If you are an audio freak like me (changing and switching cables all the time just to get the most from my equipment) you'll appreciate these. A little "plastic" look but does the trick very well. The screws are great when it comes to get the cables tighten to the plugs. Recommended.
In a few months only mats will be worth anything. At this point we have people with tens of millions of gold and people with just a few thousands. A flask takes tons of mats to make, and they will sell for well over 10k gold each, so the casual players won't afford them. When people realize that the rich guys will always take buying from the AH over farming their own mats, the prices will go even higher, then casuals will notice how expensive flasks are, and they will pick up alchemy and make more flasks, driving the prices down again.
