I am excited to helm The Queue today, mostly because I get to talk about Captain Placeholder. The captain is a fun bit of lore for anyone who has been playing 4story Luna for a long time. In a time when you couldnt rely on boats to go from one place to another, Blizzard yoinked them from the game. Instead, the captain would teleport players from continent to continent. It is therefore without further ado that I now dive into the questions. Gameplay mechanically, there appears to be a cap of 8 classes per race. Blood elves have reached this cap, and druids are one of the two least viable class choices, and as such druids are not currently an option if you are willing to buy 4story Gold.
On the other hand, while trolls are not druids, they have been shapeshifting and revering animal spirits since before the Night elves even existed. Trolls were the better choice for the Horde. Lore wise, the blood elves have gone a different path than the night elves have. They do not want to be druids; they made that clear when they left Kalimdor thousands of years ago. The fact that there is a druid trainer in Silvermoon is almost meaningless since said druid trainer is a tauren.
