110 twink guide

So I've got BFA on my main account but since you can't twink anymore I'd like to try out 110 legion twinking. Been looking on the website and haven't found the Legion expansion. Anyone know how to find it or am I rarted?

In this Post I will show you EXACTLY the way of becoming STRONG twink in 21 STEPS in Battle for Azeroth. I promise you, if you do everything correctly, this twink of yours… will either beat level 120 in duels and make them cry for their mommy, or can boost your friends or customers in Dungeons...
