I have and this is becoming pointless, you might have the time for this but I definitely don't. We're literally repeating ourselves in circles so it's best to agree to disagree, you think a singular background character monk is precedent for a large enough number of goblins to become monks based on that one Easter egg character that might or might not have been placed there as a sign of things to come, or simply, no reason at all. Goblin monks in Warcraft lore aren't playable, they're not a thing and they may never be. If they ever do become a thing, you can tell me to eat crow, but until then, you're leaving in a fantasy RPG world of "what may comes." Debating that is like running in a hamster wheel.
Even trying to decipher half your argument became a headache, it's like you saw @Super Dickmann use the straw man argument reference and started throwing that word out inappropriately, don't even get me started on knowing what you meant by indigenous. I had to decipher what you even meant by "strawmaw." Then you keep repeating the term "head canon" after you read me using it at a nausea and continued to shoe horn it in every other sentence to prop up your argument, gets kind of annoying. Even if you had a point, you might consider taking a debate class and spell check. It's not my job to make heads or tails of half of what you type.
There's really nothing else to rebuke beyond this, consider the debate over.
