I think you very much missed the point about the culture of harassment. They didn't EVEN have a parser at that point. 2 Posts above you I also said this was just the most well documented case. This isn't the only case.
The general community in Japan does not waste time bickering or having an argument to begin with, they disband/shuffle the party and move on. They have a higher clear rate anyways.
The issue is that when the harassment occurs it's serious where the person is stalked people around them are also targeted to the point of getting address info and trying to get players to commit suicide.
There was a player recently banned from the game by SE, which had to withstand a long standing harassment issue and deal with this behavior. The start of it? He copied and pasted another person's text without crediting that person. The player long since apologized for it - but that wasn't enough. That player and anyone who came in contact with him was targeted with the type of harassment I mentioned above. The victim had long ago used a mod and that was continually brought up - because culturally the community highly frowns on the use of mods in any capacity (even cosmetic).
In game for a majority of content we have some ways to get around this. Savage being being a small amount of content we have the topic of Parsing via third party tool. Where he states what his culture does basically, be quiet about it. Disband and move on. Don't waste time bickering.
If he doesn't want to feel that a death or suicide was because of a GAME (due to how his culture is) I get it. I am not exactly happy about not having one in game but I get it. I get why after seeing non stop pages of "discussion" passive aggressive remarks, and outright insults that this is not going to happen and why it just cements it. I get why one incident just also further cemented their stance.
Does it suck that we do have to keep quiet about it, and not have an official one? Yeah it does (at least for us culturally) but at least we have a tool that gives us a start even if third party for Savage - but we still have to figure out the rest (ie clipping/weaving, optimal times for rotation, fight mechanics etc) but ACT isn't going to replace community/mentor advice.
