I was playing World of Warcraft, I created a new Horde character and this eventually started happening in-game when i saw a mini raid of Level 1 Tauren Players of Different Classes. I had no idea why this happened in the game, but i need some explanation why this actually occurred.

If you were a new character in WoW, Please explain in the comments what you thought about this event. (The picture is mostly spanish so i need anyone from the Latin America Region to explain this in-game moment.)
