Can I give my main controversial opinion about M*stra? Has nothing to do with her actions in BG3 or in lore, has nothing to do with personality or her design or anything like that. My main controversial opinion about M*stra is having a God/Goddess of Magic AT ALL creates some weird problems in universe for me.
Now DnD is all over the place with the various editions but realistically M*stra isn't actually the God of Magic, she's the Goddess of the Weave which is the tool in which mortals are able to utilise Magic. But ultimately it doesn't matter cause mortals aren't gonna be tapping into magic without using the Weave or else they'd likely go insane.
But anyway it causes questions to come up like why are some people born Sorcerers, why are Devils and Fey allowed to grant Magic to Warlocks when Magic is M*stra's domain and why does she decide some people have to go to Magical University in order to cast Magic? Not even touching on all the other classes, that reasonably are tied to different gods like Druids and Nature God's still using Magic despite not worshipping M*stra. Like why are some races inherently more Magic than others? The Elven Pantheon can't gift all Elves inherent magical abilities when Magic is M*stra's domain.
Like does M*stra just decide "oh elves are magical. I'll let them be born with a cantrip." Or "that girl nearly drowned. I'm gonna make her into a Storm Sorcerer now, but that loser over there? No, he needs to get into crippling student dept before I'll grant him access to the Weave. "
Having M*stra be the sole authority on magic means these are questions I will ask now because you've told me that this ONE being is the final authority on Magic. Like how does she decide if some bloodlines are magical sorcerers? How does she decide what races are inherently magical?
Like I know they keep telling us she can't meddle too much cause Ao will get mad but in actual lore she meddles a lot, so I'm calling that putting a bandaid on their problems, they know they gave M*stra too much authority so have to try and plaster over said problem.
Realistically I would make Magic and the Weave a force of nature, even more so than the actual forces of nature because its so fundamental to the world. Its in the land, its in the air, it is life itself in some regards. Some races with a closer connection to nature and the sanctity of life are more likely to be born with an inate gift for magic and Sorcerers often come about due to interracial relations between these races and others (ie. Half Elves would have a higher than average chance of being Sorcerers, basically this would be the Draconic Bloodline Sorcerer just expanded a bit) or they were born or had some traumatic even near an area that is particularly potent with magical energy (you can still call it the Weave i guess) such as Wild Magic Zones or areas recently ravaged by Talos and Umberlees destructive natural Magic.
Then I would make M*stra the Goddess of Arcane Knowledge and Practice and the Patron Deity of Wizards. Still incredibly powerful and revered through Faerun, but not like mind bendingly so. I would make her Lawful Neutral and she encourages the study and practice of new magics, good and evil, and can grant unimaginable knowledge onto worshippers who she favours. She can still grant exceptional magical abilities upon her chosen, but just by removing her as BEING Magic and instead making Magic inherent to the world itself it removes all these issues I have and suddenly those questions just aren't important anymore. Like "why are some people sorcerers" it's just a random force to nature, the luck of the draw, they were born lucky in the right place at the right time etc. Rather than me asking "why did M*stra let these people be Sorcerers but not these people?"
I'm aware a lot of people will disagree with me, frankly I don't really care the beauty of DnD is you don't have to play the game the same way I do so you can just ignore me and move on. I just wanted to rant a bit cause this has bugged me ever since I looked properly at M*stra and her lore and started to really ask questions about the world of Forgotten Realms.
