For many younger players or those that just forgot, the original World of Warcraft had some interesting things going on, and Blizzard reminded people that some things aren’t bugs, they did it on purpose. For example, Taurens hitbox being huge or standing on top of a player while facing away will allow you to use spells and attacks. There is a whole list here of things that aren’t bugs that are working exactly as intended. I kind of wonder about the Blood Plague personally. Regardless, best wishes and may the gaming gods bring you glory.
