To be fair, when you’re among the first human Paladins, heavily armored Knights that use a divine power, you define yourself as a Paladin and then find an enemy that uses the same magic as you do - how should he have called her in your opinion?
My guess is that they will implement NE Paladins along with class skins someday. For Kal’dorei Paladins, Moonlight based skills would be a more fitting visual.
On the other hand, the Night Elves pray to an entity that emits Light and was once canoncially stated to be “the only true deity” in Azeroth, but is now probably part of the Life pantheon… I guess, anything is possible.
I would find it kinda cringe to care about the spelling of perfectly recognizable fantasy words from the game, but I am too amused by what kinds of irrelevant stuff people can argue about. I mean, what could be more important than the correct spelling of the name the Night Elves have for themselves in a language that isn’t even supposed to be their own? Can’t you read the different pronounciancions of kal’dorei and kaldorei just by looking at the word? Failing one’s scholarly duties towards the important lore texts in this detail is just a disgrace that has to be called out!
It’s not a big leap and most likely an oversight on the side of blizzard or etymological evolution, in that the term Kaldorei or Children of Kalimdor is a great deal older, while the 'dorei is mostly used by the post-sundering highborne splinter groups High Children, Children of the Blood, Children of the Night, Children of whatever the hell “Ren” is supposed to mean (probably void or shadow?)
Either way since the NE paladins from legion are Silver Hand trained and Blizz tends to be lazy when making anything other than a druid these days my money is on generic paladin.
Unless Blizzard wants to give each race some identity…which would involve Nightborne Priests and Night Elf Priests and Paladins using the white light of Elune and not the golden “holy” magic.
Same with Forsaken Priests - every spell is shadow based. (Flash Shadow and Prayer of Shadow sounds both funny and quite cool.)
