People seem to be fixating on the ilvl of the weapon and completely miss the point - that in the past Blizzard at the very least made players EARN powerful rewards through decent amounts of time investment in questing or reputation gains.
Now they are handing out very powerful weapons merely for stepping foot in the new zone. Any freshly-dinged level 120 can immediately head to Nazjatar and walk out with a 415 weapon 5 minutes later. All sources of sub-415 weapons in BFA immediately become obsolete.
This is an excessively alt-friendly move as the Azerite system was alt-unfriendly. Leading me to think they realize their screwup and are now panicking to compensate, and also desperate to hold onto enough subs until Classic releases by bribing players to return to the game in 8.2 with a welfare 415 weapon.
