Footholds into enemy territories can be done as you grow in levels and should be completed before reaching Level 120. Take the time after completing your first zone to do your first foothold. Similar to how your initial zone selection was largely irrelevant, this selection is, as well. Simply pick one and complete it to earn your Mission Table second champion. Send your champions out on missions, recruit troops, and then head back out to quest in your second zone selection.
For a new player, this will only break the immersion and spoil the 'story' of the various great storylines found throughout the game. Veteran players may want to level fast but still, revisit old places to re-experience the game through fresh eyes. How is a player to level quickly without breaking the immersion of the game? Level smart. There are ways to quickly level that apply to any area of the game.
At 96 the standard wisdom is to immediately drop what you're doing and proceed to Spires of Arak and do the quests to unlock the Inn, granting a further 20% experience bonus while in that zone. You'll want to do that eventually anyway, but I'm not sure it outweighs the quest experience from Gorgrond. However, if you decided to go to Spires immediately at 96, restrict yourself only to bonus objectives and again leave Treasures until you're 100+. Make certain that when you being the quests to unlock the inn, you speak with the quest NPC to also learn Archaeology, since it's required to collect several of the treasures in Spires.
If the new Battle.net balance has given rich players a new incentive to liquidate, and the spiking prices are a result of them trying to sell all their gold at once? Prices for tokens could settle much lower once that stash of gold has been depleted. This seems likely, because there’s a compelling new reason to sell gold, but no new reason to buy it. Blizzard has a good way to drain those gold reserves from the market.
In 2015, Blizzard started letting players buy gold from each other using WoW Tokens, to try to control the process and mitigate damage. “Time is money, friend — but sometimes one is harder to come by than the other,” Blizzard says on the official page. “Now World of Warcraft players can use the WoW Token in exchange for game time or Battle.net Balance!”
