In my opinion if parsers are allowed, the forums would become a numbers to numbers discussion. Job/classes complaints would be about which class does lesser numbers then another and threads beating each other up because they can't do a set amount of numbers. Parsers would become the meta of justifications for nerfs and buffs, for changes and even QOL. No i didn't come to this game playing numbers, i came to it because it provided many more types of content outside of numbers. That being said parsers would probably have a minimal effect in-game, i mean no one bothers to really explain if someone is doing bad/not pulling their weight and you don't have all the time in the world to teach a player their rotations if they can't hit their numbers.
