Your actual problem seems to be that BioWare shows us a world too realistic. In our world, minorities suffer. They are usually oppressed, leading to them developing an underlying hostility, which again leads to seclusion. Not seldom do they have a lower education therefore. They often lose their original culture and language, trying to keep it alive but often messing up. I know little about Jews but I did see other minorities and what BW shows me is something I have seen in real life. Being as underprivileged as minorities often are, it is just realistic to show that they can hardly hold a candle to majority representatives, who have a better education and better resources. Not nice, not funny, not motivating, but realistic.
You however wish BW showed a different world, a world where the minority suddenly surpasses the majority. But how would that work? If it worked, how would they still be such a minority? (If all poor Brazilian slum kids rose to become great football players in Europe, subsequently helping their folks back home to build and improve, how would there still be any Brazilian slums left?)
Please stop twisting and omitting my words.
First, how "realistic" is this world when it has magic and giants and dragons?
Second, it's not that this world is "too realistic," it's that it's "too realistic" only for the minority/disadvantaged characters but not for human characters. It's the double-standard regarding the "realism." It's that BioWare has written it so that human characters constantly find themselves in fantastic, out-of-the-ordinary circumstances that let them gain more knowledge and advantages than the average human, while they write it so that elves never get such fantastic circumstances or lucky advantages.
You want to talk about "not realistic"? Most human characters don't know that much about ancient elven lore and magics either, so it would be "unrealistic" for a contemporary human like Morrigan to be able to gain such knowledge. But Morrigan didn't have an upbringing typical of "most humans"; she was raised by Flemeth, and given unusual access to such knowledge. It would also be "unrealistic" for a human apostate to be raised in plain sight of the Templars (since most child mages tend to get caught or killed, or possessed by a demon if unproperly trained in magic), but Hawke didn't have a typical upbringing of most Andrastian human mages. Malcolm Hawke had been a Circle mage who had escaped, galavanded around the country as a mercenary, then settled down and used his Circle knowledge to train his children so they could hide and control their magic. (To say nothing of when Hawke gets to Kirkwall, where apparently none of the rules of the city apply to him or her.) But, elven characters never get similar chances by BioWare; they all get the "realistic" upbringing that keeps them down while human characters like Morrigan and Hawke get the "fantastic" circumstances that let them rise up and gain access to more knowledge, opportunities, and circumstances than most humans in their socio/economic race/class should "realistically" gain, while elven characters never get such breaks.
And I never said the elves should all suddenly surpass the majority. But in terms of knowledge of their own lore/culture and utilization of their own magic/technology, is it really too much to ask to have an occasional elven character know more than a human character? Of course it is. Since the Dalish have spent centuries doing nothing but researching and reclaiming their own culture, of course it's too much to ask that they would know more than a human mage who only started skimming a few years ago.
Of course sheltered human mage Finn should be able to effortlessly translate eluvian and piece together an ancient elven tracking ritual, just to show up the Dalish warrior in the party. Of course when human hedge witch Morrigan repairs an eluvian based on scraps of research she's done over the last few years, the narrative treats it like she knows exactly what she's doing; but when Dalish Elf Merrill does the exact same thing, the narrative treats it like she's messing with powers too great for her to understand. (It's only her people's magic and technology; why should she know what she's doing?) Of course the human hedge witch Morrigan info-dumps the Inquisitor with knowledge of ancient elven lore, ruins, and technology (and most often ends up drinking from the Well, gaining the last scrap of ancient elven knowledge), even to a Dalish Inquisitor.
They couldn't write her to be elven or write in another elven character to be the expert on ancient elven sh!t; not when they can have human characters constantly know more about elven stuff than the elves do, and have human characters constantly better use the elven stuff than elven characters can. That's "realistic."
