I'm not sure if this changed after TBC because frankly a lot of lore has been retconned. But the reddish skin and reddish hair were also due to fel exposure, not just the green eyes. Once again, it's very comparable to Orcs in terms of corruption.
Mag'har - High elf
Normal Orc - Blood elf
Fel Orc - Void elf (Yes I know Void is not fel, but it's a corruptive dark power nonetheless)
Normal Orcs are identical to Mag'har except for having green skin. Blood elves have less physical changes but that doesn't mean they're not corrupt. Fel Orcs however, are completely warped by Fel, just the same as how Void elves are completely warped by the Void.
If they renamed the Void elf race, changed their racial to not automatically turn on, and gave High elf customization to Void elves, that'd be fine with me.
