While parsers can be awesome, Yoshi-P will probably not add them for the reasons many people have said in this thread. His design philosophy is all about making sure the players feel comfortable while playing the game. Because there is a chance someone could be rude while looking at an in-game parser for their party and yelling at another player, I doubt this will ever be added. SE will be opening up the game for 3rd party tools, but I have a feeling parsers still won't be acceptable. If you really want to know your group's dmg output, use a parser and play roulette with the ban hammer.
