I thought to create this thread based on my own opinion, with some lore, to why I think San’layn or Dark Rangers wouldn’t work as customisations options to Blood Elves. But please do take note, just because I created this thread, does not mean I am against Blood Elves recieving anything.
Who are the San’layn?
The San’layn (sometimes spelled in lowercase, also known as the Darkfallen) are vampyr blood elves in service to the Scourge. They used to be among Kael’thas Sunstrider’s greatest followers, until they were raised into undeath by Arthas following Illidan Stormrage’s failed assault on the Frozen Throne. During Battle for Azeroth, a number of San’layn led by Blood Prince Dreven were given a chance to join the Horde by Warchief Sylvanas if they could work with them, but Dreven was killed during his mission.

Who are the Dark Rangers?
Dark rangers are undead archers in service of the Forsaken or Sylvanas Windrunner. These cunning individuals, adept at manipulating opponents, are mainly composed of forcibly raised Farstrider rangers of Quel’Thalas. They now enjoy nothing more than sowing dissension and hatred within the enemy ranks. The Forsaken use dark rangers as elite agents or as the personal guards of Sylvanas. They had a great presence in Silverpine Forest and Hillsbrad Foothills. Some of the dark rangers joined Sylvanas after she abandoned the Horde at the Fourth War’s end, but most seem to have remained with the Horde.

Why do I think that San’layn wouldn’t work as Customisations for Blood Elves?
As everyone knows, the San’layn were killed off in the Battle for Azeroth campaign by the Alliance. And considering they were given a chance to join the Horde ranks by Sylvanas Windrunner when she was the Warchief, they were there on behalf of Sylvanas, not the Horde. But now, Sylvanas Windrunner is not the Warchief of the Horde, and since the Horde is now more of a council between each racial leader, it is highly unlikely that the San’layn will be given a chance to join the Horde. Plus, since the Blood Prince Dreven was killed also in the Battle for Azeroth Campaign, there is no clue to how many San’layn remain and who, if any, is their new leader.
Why do I think that Dark Rangers wouldn’t work as Customisations for Blood Elves?
Dark Rangers are just basically undead, and as well all know, Undead is a condition, something which won’t really work good for Blood Elves, as Blood Elves doesn’t suffer from this condition. I think Dark Rangers would work better as Undead Customisations assuming that another model will be added to Undead for Dark Ranger customisations to work. And considering also during the Battle for Azeorth campaign, there is also Kael’dorei Dark Rangers, which were raised after the Horde killed many of the Kael’dorei and destroyed there home, this isn’t something which will not work at all for the Blood Elves.
CLOSING STATEMENT:
Basically, I’m just stating my own opinion on why I think San’layn and Dark Rangers customisations wouldn’t work for the Blood Elves. I do want to see more customisations for the Blood Elves, but I do not think San’layn or Dark Rangers are the way to go. Plus, with Dark Rangers and San’layn only having certain classes within there ranks, it wouldn’t make sense for other classes to be with them in terms of customisations, such as Paladins for a prime example.
