I have 5 chars at 110 and 2 of them geared, 1 is 810 and the other 2 are ~800. I just don't do daily WQs. I level because at some point I want other chars 110. I refuse to participate in Blizzards insane rng BS. If I get a legendary fine, but I ain't farming for it. Might as well farm Time-Lost Proto-drake. I gear through raiding, and some items mythic dungs.
Detaching oneself from the ridiculous grind can be difficult if friends/guildies have AL25+ and you're around 20 or something, I appreciate that. But I have a life.
