So, if Elven magic (or Aerneri magic, I guess) is basically standardized (everyone performs a spell the exact same way), I can see that having a significant effect in terms of efficiency. Repairing an enchantment won’t take some guesswork to figure out where the syllabic emphasis or whatnot was. If a group of elves is doing a ritual and one of them keels over and dies, another one could take over, because again, standardized magic.

The effect of this standardization, though, is I feel as if elves would have more magic, more enchantments, than in Khorvaire. Perhaps a smaller variety of very common enchantments, but I can certainly see some being as ubiquitous as, say, a lightbulb or indoor plumbing.
