TBH I care so little about DPS numbers I just pulled them out of my ass. I don't mean to be antagonistic and I am more annoyed at the Tommy the Tanks I've met in the DF than at you or anyone who uses a parser personally. Said Tommys aren't necessarily the ones who pull DPS numbers on you but they are the ones that sprint ahead of the group without warning or checking to see if the group has AoE damage besides a whm and expect the whole group to follow them and then yell at the healer (me) for not having some psychic link and knowing exactly what he intended to do. I've met a few of those and I don't like them very much. These are the people I forsee using parsers in such a way as the example given.
Because we have very different philosophies on what makes a game fun. You like numbers and making sure everything is working as optimally as possible, whereas I just like to go in and have fun. Am I going to purposely fail or sit and do nothing when I could toss out a few dots or stone IIIs? No. But I don't want to have to stress out that I didn't get exactly 3 stone IIIs off during X window when I only got 2 off. And with someone like you on the team, I would worry about that whether you yelled at me or not and that makes things less enjoyable for me.
I do prefer a casual team of people who go into fights to have fun. I had to do coil mostly in the Duty Finder and I have just met some players in the DF who take the game way too seriously and they stress me out because I just wanna relax and enjoy myself.
Do I hate people who have parsers? No. I've been parsed myself and have come out decently according to the person who parsed me. But I don't want the game to become something where everyone is obsessed with numbers that I have to feel intimidated by entering the duty finder in case I get someone with a tree crammed up their butt and have to worry about every little thing. I am a person who does just about everything via the duty finder. My FC is extremely casual and most of them do crafting or goof around and very few raid. But my experiences raiding in FFXIV thus far have been more stressful than enjoyable and that has pretty much ruined raid content for me. If that starts transitioning to the DF content such as dungeons, I would very likely stop playing. To me, when a game starts causing stress or becoming a job, it's time to stop playing-- it's not a game anymore.
But I will turn your question back to you: Why should someone like me be forced to play under the shadow of a parser when you guys who want parsers can join groups of your own like minded individuals who want to use parsers to improve and play optimally?
Am I missing something? Because I've done both and I certainly don't remember getting a special prize for them. Is it really that important to a dungeon run that these things happen? Do I get brownie points for getting both DPS's out of doll form with a holy and assize at the same time during the first dollhouse phase because I don't remember getting those either. Perhaps this time issue is another thing we will just have to agree to disagree on.
