How do I have fun in this expansion?

I’ve spent 3 months gearing up a hunter just to find out that every guild pretty much has their teams already set. After realizing I couldn’t raid much even when I pull 60k dps, I qued for a few bg’s and did some world PvP only to find how much it is dominated by alliance.

Looking at how the low levels are, It seems roll and alt and use the buff to level them up quickly for Shadowlands
