I can see your points for why you think a parser is needed. However, if PC players communicate with other PC players and PS4 players, then I don't see a problem with the current parser system.
Not sure if it is a valid comparison or not, but when I played WoW I did enjoy having a parser for a friendly competition between guildmates/friends in who can put out the most dps. The downside to that is, there are always those few players that use them and turn them into a "I have a bigger dick fest." But then again, what would WoW be without that? So if suppose that if would stay a friendly system and only be used to help people out, then I would be less opposed to it. However there is no way to guarantee a parser would be used only for those reasons.
