Oh I know. But they do not depend on 1-2 members of their race for their direct survival like San'layn do, either. And unlike the San'layn, they are a very well-accepted part of the Alliance. And comparatively, there are a lot more of them.
Losing Dreven is comparable to having Vereesa Windrunner killed off alongside the entire Silver Covenant perhaps. But comparing it to the loss of a random lodge in the Plaguelands? No... it's just a bad analogy.

What are the elves even supposed to be? Vulpera sure, but if you are suggesting night elf dark rangers are the new allied race for Alliance, then lol. That is fan fiction level stuff, and that's being generous.
