How would an optional, official parser be toxic?

[Legion88]

All this being said I think XIV should give better tools to allow players to access their own performance. At the very least the game should display personal dps. The stone sky sea dummies should also display dps instead of just giving players a timer to go on and forcing them to go to a third party tool to glean the true meaning behind their kill time. Additionally there should be more analytical utility given to target dummy furnishings, because right now their function is too basic. Currently pc players are at a distinct advantage when it comes to analysing personal dps and I think SE should address this in some manner.

But introducing a normal parser in which you can compare yourself to others at a glance? No I'm strongly against this because my time in WoW showed me the long-term ill effects from it. The gain doesn't outweigh the negative aspects.

Stop right now.
Dummies have only one use: training muscle memory.

We don't really need a parser, because it is already ingame: the battle log.
The only problem is, that the battle log is hard and to time consuming to read and analyse.
We need an analysing tool like fflogs and xivanalysis to transvere the data from the battle log into easy readable and interpretable display with timelines, graphs and charts.

Informations from a dummy can only be used for a xivanalysis style autointerpreting and hint giving for a base improvement of the jobs knowledge.
