High Elf and Blood Elf druids are ridiculous.
They come from Highborne, where druidism is near impossible to find in that arcane obsession.
Blood Elves have fel corruption. Being a druid would never work.
You see that shit in The Botanica? Look closely.
Do you see the "engineers" and the machines used to manipulate and experiment on plants?
That's not druidism. That's mana siphoning. Do you even know the lore of Tempest Keep? Gaining any type of magic they can cause they're addicts.
These aren't Lor'themar's Sin'dorei. These are Kael'thas's Sin'dorei. They have nothing redeeming or natural about them.
They are not druids. They are not practicing druidism. They are stealing and experimenting on life forms for their magic.
But hey, if you want to be ignorant lore breakers and not realize fel corruption or any type of magic corruption (like the Wretched) does NOT encourage wildlife (Seriously, go look up plagueshifter) to accept you as a druid. In fact, they're more inclined to attack you.
But you know, people don't want to take a look at the lore behind shit. "But he shape shifts!" No fucking shit. If you steal that magic you can probably use it.
