5 minute average queue time.

That's trinity design for you.

I mean, they could make content where tanks and healers aren't needed, just remove the unavoidable damage. But then tanks and healers would become pointless. You need to force them into groups via content design so they can viably live out their niché fantasies, which in turn means other people have to suffer in queues for their sake.

Or maybe because "Everyone's a DPS now!" leads to simplistic design which ends up being less interesting for everyone.

But, I mean, those games do exist. You can load up GW2 and/or BDO any time and start playing.
