That's not necessary needed I believe .
In the Ministry you can do a part of the Main Quest, but that will not mean you be forced to go as fast as you can after that into the Hall of Echoes !
O no, take your time, talk & walk as much as you wish,
Trade & fight,
Solve quests you like !
My hero was around L 31 - 33 when go to the Ministry and help Zandalor finding the Shield . Other gamers go earlier or later on, it's all up to you
