I am more in line with Ken Titus.
So far early access to Legion content is...
-Demon Hunters are cool, the skillset is going to take some getting used to
-Demon hunter starting zone is nasty af and loaded with stuff, I didn't even know where to begin.
-Demon Invasions are a gigantic clusterf--k with too many people in one area so everything freezes up, but its only going to get worse launch day
-Broken Isles Pre-Quest is fun, cut scenes are amazing, can't wait for full access.
