It's just that this game is full of toxic players, but not in the sense that you see in WoW where they straight call you out for bs. At the end of the day official parsers being in the game or not doesn't matter in the grand scheme of things imho, if anything it would be a positive and would create a more competitive environment for the respective high end content with less of the usual clownery - probably. Casuals will cry tho and this game will be set aflame by the firestorm it creates so probably not gonna happen.
