I think the most important point he makes is that new players need something to aspire to.

Dumbing down jobs at high levels doesn't help anyone - the people who are already high level aren't new and don't need the hand-holding, and actual newbies have hundreds of hours to grow into jobs as they go through MSQ.

Granted, some people boost to get into endgame raiding asap, but those aren't the kind of people who need hand-holding either.

All they're doing is dumbing down jobs for people who don't need it while simultaneously removing future satisfaction from those who haven't even unlocked that complexity yet.
