Gaming is fun, and fun is for everyone
A few things to keep in mind:
• The set was originally designed as a generic D&D themed magic set before the decision was made to put it in an actual D&D setting.
• Forgotten Realms was probably chosen as the setting to put it in because it’s the assumed default setting in 5e.
• This set is probably being targeted primarily at magic players and secondarily at 5e players.
• 5e does not currently have a 5e setting book, and it is not on DMs guild.
• Mordenkainen’s name appears in the title of a 5e book and he has appeared in a published 5e adventure path. Vecna has two artifacts that appear in the DMG, and Acererak has been the primary antagonist of a published 5e adventure path.
Agree with all your points. I just get a little peeved when fans of FR brag about "stealing" other setting's material... just adds fuel to my belief that FR has become an all-encompassing kitchen sink with a barely consistent premise.
And I say that as someone who runs a game in FR!
