This can be a little hectic if you're on a PvP server since most level 50's are in this zone, but that's for a good reason. There are several quests for both Horde and Alliance but among the better ones are the Cauldron Quests. There are four of these, I believe, that will end up giving you good experience. Complete as many quests here as you can before we head out to the next zone.
Island expeditions - Set sail for the previously unmapped isles of Azeroth. Battle in groups of three as you race against cunning rival intruders—or enemy players—to collect the island's resources. Constantly evolving challenges await as you traverse frozen landscapes near Northrend, open the gates of an abandoned Gilnean castle, navigate a war between elementals and more. Can be done either in PvP or PvE against advanced AIs.
Nov 6 are twinks an issue in high level pvp hello i have not played since cat and when i found out accounts were upgraded to the last xpack i started played without a sub. i mainly like to pvp but the 20-29 bracket is won by who has the most twinks so the result is either a slaughter or a carry neither of these are fun for anyone who likes competitive gameplay. i also feel like i have little to no impact on the outcome or outside running flags (if i'm not 3 shoted by a twink). it seems no matter how skilled the player is if you don't have the gear you're not going to do well. anyway is every bracket like this or is this just a issue with 10-19/20-29 brackets? i know 10-19 is unplayable if your not twinked. i'm sorry i didn't sub last xpack it sounded like pvp was better than.Piale3 Nov 6
The old popular example was the This item differed on my server from a high of 6k to a low of about 3k. When the price was down at 3k, I would buy a few of these and just wait a week. Throughout the week, I would put in trade and the auction house that I wanted 6k for it. I would then immediately go onto an alt and say that I only wanted 5200g. Sometimes, I would get the 5200g and be a very happy man, other times it would take more patience. However, almost always, by the end of the week, the other sellers had reposted for around what I wanted. This gave me a huge advantage. Now, the price ceiling was no longer 3k on the auction house, but 5k. I could now easily sell the few I bought for 4 or 4.5k, which is a huge 50% profit from the 3k I originally invested.
Alchemy is a great profession for gold-making as the main outputs are consumed on use, this means that there will always be demand for new potions and flasks. The old world recipes are also very profitable. Sadly I don’t have Legion alchemy so I can’t personally help you. The best guide I was able to find on the internet is this video guide by Ninja Kuma.

First of all, the value of transmog is decided by rarity and how they look. Some items like Minenarbeithut der Tiefen or Pendel der Verdammnis (they can drop in Uldaman) are worth millions of gold. They are worth so much, because they have a really small chance to drop. Other items are bought well because they look good. Best example in this case is the Glorious set, its legplates Glorreichen Beinplatte reach a 100.000 Gold value easily.
