If you really think that night elves have shared all their knowledge about druidism, you are wrong We even expierience such fact, in the suramar-questline.
The night elves sit on their “Throne of Knowledge” about the possibilitys of Druidism and don´t share everything, for example, worldtrees and how to grow one.
It is not at all about who has defeated how when where! They still found effective strategies against the Horde, and cost the Horde more troops than the other way around, they effectively made the Horde’s life hell with an absolute outnumbered strategy.
The point is that they do not always take strategy X but use a variety of strategies to win.
Well, magic beats technology in Warcraft, just look at what the voidstones did to the goblins’ technology.
Magic > Technology
You may be forgetting here that even one of the greatest powers of the night elves may only be used to a very limited extent…they can terraform.
Only they have this knowledge, no one else. Only they have used it, no one else. If you list all this here, you also forget that the night elves are not allowed to use everything that has been attributed to them by Lore and has already been shown.
And sorry, but its exist no more deadly weapon as…Terraforming, because you will kill everyone, everyone, in this place to form this place in your own imagination. To create new stuff, you have to change existing ones. Val’Sharrah was only completely destroyed and ruined 10,000 years ago, so they didn’t have to kill anything there to create new.
Val’Sharrah is such an example, or the barrens, the night elves used their ability for good, but no one could stop them, if they use it to kill someone.
PS: And now I’ve done it, I’ve gone into a silly power discussion!
That was my last answer to this now, because I’m actually about the adaption and not about “who has the biggest imaginary pe***”
i could kick myself right now.
