super late reply, but i mean if you where comparing it to like kiting, kiting is a game mechanic and is perfectly legal because its just some classes have the ability to do it and is a mechanic. But if you where just sitting on a ledge perching a raid boss that cant hit back because of bad coding in the game. Wouldnt you consider this cheap? Its technically using a bug within the game to better ones self and if thats ok whats to say thats any different then using any other bugs to better ones self? Sorry just want some clarification.
