They were changed, from Cdev:
Q: How did the blood elven fel eye glint become so widespread? The Warcraft Encyclopedia suggests that Rommath only taught the blood elves of Azeroth about how to siphon arcane magic, as most of the populace would likely be âhorrifiedâ if they knew the true extent of Kaelâs dealings with Illidan.
A: The situation regarding blood elf eyes is, in fact, extremely similar to that of the green skin of orcs: just being around heavy use of fel magic turned the eyes of the blood elves green. You could be the most pious of priests or most outdoorsy of Farstriders, chances are, if you were a high elf in QuelâThalas or Outland following the Third War, you were around fel energies, and your eyes would turn green. Like the orcsâ skin color, such an effect would take a very long time to wear off. Fel magic works a bit like radiation in this sense; it permeates the area and seeps into anything in the vicinity. Anything near a source of fel magic shows signs of slight corruption, it just so happens that high elves and orcs manifest it in a very visual way.
- And this is where some elves started to separate their ways :
Counteracting magic withdrawal The elves had been sustained by the Sunwell for several millennia, during which time they had become dependent upon its power. The need to feed upon the arcane only became truly apparent after the Sunwellâs destruction when the elves were cut off from the constant flow of magic the well suffused every fiber of their beings with.
Bereft of their Sunwell, the blood elves were forced to deal with their addiction differently. Through Illidan Stormrage (who maintained that magical addiction cannot be conquered by any means, only sated), Prince Kaelâthas acquired the teachings of stripping arcane magic from other sources, be it mana-bearing items or creatures. This process was dubbed the " [Mana Tap]," and became an important and increasingly essential part of the elvesâ lives. Kael instructed Rommath to spread these teachings back home in QuelâThalas, as a way to sateâbut not cureâthe elvesâ addiction to magic. The knowledge was passed down until all blood elves had learned the techniques necessary to draw arcane energies from crystals, artifacts, creatures, or even mortals who commanded such power. This technique was a cause of contention: some deemed it as immoral, while others callously overused it and were physically warped into what became known as the Wretched.

- And fel crystals in the Silvermoon werenât there just for the decoration sake, just found this on the reddit :
âKristine Denny says: Your choice of decor is intriguing, Kelemar. Tell me - why the arcane frippery?â
âAmbassador Kelemar says: It is not simply a beautification measure, but also a morale booster. It demonstrates to our people that we have a great deal of power at our fingertips, and with it⌠we can do nearly anything.â
The Elves of Quelâthalas have always had an intensely magical city. Perhaps they could have just had a normal city logistically, but none of them would have wanted that. They /wanted/ a magical city as thats what they were used to and comfortable with.
