DPS meters and why they're necessary

[givemeraptors]

Tell me how you observe 3 or 4 people's buff/debuff/dots while tracking boss's abilities when you're in a progression party (where dps numbers matter) and not an overgeared-for-content party. Some mistakes are more glaringly obvious than others but even your point of view limits you on what you can and cannot see.

I actually think it's the opposite. I tend to pay more attention to what my party is doing in difficult content than in easy content. This is because everyone needs to be way more up to speed for progression. With the exception of going in blind, most fights in this game have incredible easy mechanics. Whether the other 7 players can keep up with that while doing their job? Well... this is why I pay attention to my party members.

I had suspicions that my FCmate was a terrible dps player. I acquired parser information, analyzed it, and coached this player. Immediately there was improvement and they ended up enjoying the class/job even more. They would've gone on forever in ignorance of their terrible performance. Meters pls.

Nothing in this situation required a parser. It could just as easily be: you had suspicions, you coached them and saw an improvement i.e. things die faster.
I would also like to point out that these kinds of things are more relevant in FC/Progression parties where you're more likely to observe someone's playstyle over time and have a better sense of whether they need additional help.
