So because some people will be jerks, no one should get it (officially)?
Some people are jerks in dungeons if you mess up a mechanic. Some people are jerks in pvp. Some people are jerks in hunts. Some people are jerks just talking in chat or novice network. Some people take advantage of FCs. Heck one person was being a jerk in the gold saucer by dancing right on top of the NPC to handle the jumping GATE challenge in to making it difficult to hand in.
If you take down anything someone could abuse to tear others apart, you have nothing left except a single player game.
Besides there are people who want an official parser that works only for them (not the whole party, just "me") so they can see their own numbers and not anyone else's. They could then compare with people they trust by chatting and asking about their respective numbers. What about that version?
