Battle for Azeroth has been a very alt-unfriendly growth, but as the busy Patch 8.3 grind begins to repay, it may be time to wow classic gold dust off a second character. Keeping up requires some hefty attempt the first week, as you move through the intro quests and do your very first collection of Horrific Visions to get your new Legendary cloak leveled. (Tip: Every time Magni informs you to meet him someplace, speak with him again. He does not offer you the chance to skip situations until you do.)
But after the first effort, you can keep up within an alt by performing the weekly major attack, the biweekly lesser assaults, one Horrific Vision, and whatever daily little visions you manage to squeeze in--these tend to just take a couple of minutes. You're going to wind up with just two essences for your Heart of Azeroth legendary neck just from performing these steps, plus another if you take part in this Ny'alotha raid on such character.
The Worldvein Essence, accessible by running the weekly Island Expeditions pursuit, is comparatively easy to obtain and was recently buffed considerably, becoming of the best essences for a few courses.
Essences stay the stumbling block for alternate characters, but it's possible to receive an alt in reasonable shape in 8.3, if not perfectly min-maxed.
