It is definitely an issue. I’ve staved off the extreme boredom by leveling all of my 110s to 120 (have 5, 2 more to go) that way later on in the expansion I’m good to go.
The bottom line is there is just absolutely nothing worth logging into WoW for right now once you get the few things at 120 out of the way. Legion wasn’t great either at this point, but eventually turned into my favorite expansion so hopefully that is what happens with this one.
Flying is a major step in the right direction, so hopefully part 2 isn’t time gated to hell and back.
