Any decently geared 90 can complete a Pit of Saron trash mob run in 3-5 minutes. Each mob in the heroic version has a chance of dropping a Battered Hilt, which sell on the auction house for around 10k. Video guides will show the best route to take to pull all the trash mobs at once if you're a class with good AOE; other classes can simply pull less mobs at a time and loot as they go. While this method is a little less reliable than farming Vale-- after all, you're left to the mercy of RNG gods-- it has a higher chance of huge windfall because you could get a multiple hilts every run. Pull the mobs, burn 'em down, and cross your fingers when you loot. On top of the hilts, there's plenty of vendor trash, BoP epics for enchanters, and even a trinket that turns you into a gorilla. You will have to have completed the Forge of Souls in Icecrown Citadel to access this particular dungeon, though.
Good news for WoW fans! According to what raiditem.com know, World of Warcraft's latest expansion Battle for Azeroth has been as one of the best PC games in 2018. That at least tell us that WoW is valuable and WoW deserves our money on WoW gold. At the end of this year, we are lucky to experience ancient potion called "Elixir of Tongues" which allows us to understand the opposing faction in chat.
There are also numerous gold-making guides available for World of Warcraft players. Currently mmobux recommends Killer Guides' World of Warcraft Gold Guide, which covers a broad range from daily quests and professions to making gold while leveling and auction house trading. 'Standard' farming spots are covered as well, making it an interesting resource for bots as well. Yielding up to 500 gold per hour, the strategies are suitable for players of all skill levels. If Killer Guides keeps the guide up to date, it probably will become a valuable resource for professional farmers as well. There also seems to be a German-language version available: WoW Gold Guide (German)
Mythic+ rewards will also go up by 30 item levels; however, during the first week of Season 2, rewards from end-of-run chests will be capped at Mythic 6 quality (item level 385), and the chest you open next week will contain Season 1 rewards if you do a Mythic+ run this week. (So, for example, if you do a Mythic 10 during the final week of Season 1, you’ll get a Season 1 item level 380 piece and 60 Residuum from your first Season 2 chest.)
