A modern game is competing against games like Fortnite, Blackout, League, Dota 2, Overwatch, HotS, etc. I’m not suggesting all these games are exact cookie cutters of each other, but if you look at what’s popular, they do have a common theme.
Think about one of the above games. What happens is you queue up, you’re immediately dropped into a game and you play. The queue times are generally between 1-2 minutes for roughly 10-30 minutes of play time with a lack of “play” time between 10s and 90s.
Compare that to the current state of WoW where we have a lot of idle time. You do a WQ (15-120s), you blow your whistle, you hop on a FP to the next WQ. You fly for 60-90s, ride another 30s-60s to another WQ which you complete in 15-120s.
How engaged were you during this process? At the extreme, you started at X point, blew your whistle, spent 60-120s flying (disengaged), rode another 30s-60s (partially engaged unless you have vast difficulty traversing the terrain) to actively engage in doing something for 15-120s.
With extreme values, we’ll say it took you 5 minutes (which isn’t that bad of an estimate considering I can usually whistle after every WQ). At the extreme, you spent 3 minutes of getting to the thing you want to do to do the thing to repeat the process.
That’s a 40% engagement vs 60% disengagement. I’d say that WQs are sort of a special case, but, I honestly have always felt more engaged flying to WQs than without flying because it reduces the travel time. Your mileage may vary, but that’s my take.
It’s fairly comparable to Fortnite in a way, too. You can either drop where everyone drops or drop far away from everyone and play running simulator.
