Nothing quite like when a friend returns mid through an expansion and you need to mention the eight systems he needs to get involved in and what he needs to start grinding like in BFA.
Oh yeah you gotta go back and do old content to get rep, yeah then you unlock a thing called essences. Right but then you gotta level your neck, yeah you just grind old content. Right but you can’t use your gear unless you power up your neck but then you need corruption okay but not too much right because you gotta grind new content dailies to get keys to run visions. What are visions? they are like mini solo dungeons for your legendary cloak, yeah you have a legendary cloak which lets you use more corruption. It makes you stronger and you can buy it on the AH
