I appreciate the acknowledgement.
As I mentioned prior to your post, while leery, I would not be opposed to a personal (self only) parser that had no "announce to chat" option. Such a thing could be used by players for personal betterment without clogging chat with unnecessary chatter. One of the things I dislike about parsers that show you everyone's numbers is that it often turns a "cooperative" situation (a raid for instance), into a "competitive" one (dps trying to one up each other). And while some amount of competition can be healthy it often leads to players making reckless decisions for the betterment of their personal numbers at the cost of the overall group's performance. I dislike chat announcements because you inevitably end up with:
The "star of the show!" player who asks "anyone have meters?" only when they've topped them and they clearly have their own but want someone other than themselves to post it to chat.
The ever classic "elitist jerk" player who tells those who do poorly just how bad they are and that they should just quit the game cause there's no hope for them to be anything but bad. Never once offering any sort of constructive criticism or advice on how to improve.
These types of behavior are most typically seen in dungeon/small party level content where bleeding edge performance isn't required and some players are still learning about the game. I particularly dislike the second type of player because I don't like seeing players attacked because they might not be the best, in content that doesn't require the best, and contribute no worthwhile feedback to help others improve. It's akin to putting together a group requiring everyone to have an ilvl above 200... for an instance that has a min ilvl requirement of 180 and only drops 195 loot. Which is ridiculous.
Heck even in our pleasant community we have bad apples. I primarily heal as SCH (and lately WHM) in this game. I had a Snowcloak run where the tank was obviously not confident in his tanking ability. He kept his pulls small and sometimes lost aggro on a mob which came to me but he was quick to pick them back up. While this run wasn't the fastest I've had, there were no wipes and no deaths. At the end of the run the BLM in the party says in chat something along the lines of "You should give up tanking you're horrible at it." and leaves the dungeon. THAT was his "contribution". I can only imagine what he'd say to other dps if he had meters to see "how much better he is than them". That's what I want to avoid in ffxiv.
