Unpopular opinion maybe but Shadowheart should have been even more special - she should have been Aylin's sister - and I suspect she was in some early draft. This puts her on par with the other origins. Otherwise why would
Shar put Viconia - who was the most powerful Sharran in the realms in charge of her upbringing. Why sacrifice waterdeep's Sharrans and make the entire focus of the Baldur's Gate Sharrans cloister raising SH? Viconia tells us: Shar wanted to see one of Selune's children turned to the dark. But this line isn't supported by any another dialogue in the game.
At present she's the least remarkable of the origins.
Astarian can become the vampire ascendant - this scene seems to be ripped from Blade 1 where the person who completes the ritual becomes a vampire god. Lae'zel becomes the leader of the anti Vlaakith gith and/or the right hand of the Gith messiah. Wyll is a first name basis with his patron.
While evil SH becomes the head of the BG branch of the church? Meh.
Imo the problem isn't that the origins are too special but that the Tav isn't special at all. But then again I chose to become a god in both BG2 and WotR so that shows that I have bad taste.
