We do not know we can speculate and postulate that open access to data would lead to an overall increase in toxicity, or maybe things would stay roughly the same i terms of how toxic things are with being removed ‘ barred from groups due to information. I would not say I have an argument per-se cause my position is this will never change I am mostly just talking about how I wish things were.
We only know based off other games, other balancing structures especially where character progress is tied mostly through gear. In FFXIV endgame raiding is not much the focus of character development. You can reach the height of character development ties to story never touching savage especially with things like relic weapons.
This game does not really have a FoTM structure and encounter design is heavily scripted so I personally cannot say with 100% certainty that adding parsers would lead to a higher when accounted for increased availability. Unless you are saying that the overall increase is all that matters which is unfair comparison since of course with increased availability more issues of toxicity would occur. If I were to make an argument my position would be that the overall increase in availability would not increase the amount of toxicity that would statistically differ in terms of what GM’s / community face now.
Sure if we take into account the requirements to make a system that works for console that is a different story altogether cause I have already stated this would never happen so I was not taking into consideration since I did not think this was a debate on if they should or should not add them. Cause that is irrelevant because they never will. I was talking about how I do not agree with the general philosophy behind their choice.
Though it is funny not saying you are doing this but in other cases some like to say one cannot compare FFXIV to other games yet when it comes to parsing we are quick to site our negative experiences in other games as a reason to not have them.
