He's definitely wrong about 45 minutes. You have to wait for xur before you can do the urn quest to get the gauntlets that are no better than what you can buy from vendors.
And you have to wait for the raid gear to drop.
And you have to wait until you have enough radiant shards to level up the one set of gear you're transferring between all your characters before you can hit 32.
So yeah, all that waiting adds up, yo.
