Looking at FFXIV community... I don't see the point to add a complete ingame parser. I mean, you can check and test your rotations with SSS.... with remaining time you can compare with other players. The thing is.... what about your performance in dungeon or raid... maybe in dungeon as pure casual content designed for casual players... we don't need anything more. But in Savage content they could add something like "Resume Window"... If SE doesn't want to show Damage at Raid... they could show overall rating by
D, C, B, A, A+, S. This rate could be calculated in terms of role and specific job.
Anyway a Window like the one showed at PvP for the end of each Savage try could be fine too. Specially for PS4 players who just want to improve their performance.
Many times I've read ppl in this forum complaining about "SE don't add parser to this game, bla bla bla". I hope that these kind of players just understand that this petition should only be for dungeons or casual content; and obviously they understand that having ingame parsing for trials extreme or savage content could be fine to avoid these kind of toxic players who join to a primal pony/bird/wolf farm, then underperform as hell and even think that they can complain about group performance... I'd like to say to one of these ultra low DPS "hey guy, you are underperforming in a wolf farm where we are demanding high DPS only... pls look for another party for your play level".
The thing is... these kind of players usually ruin Farm partys. Well... these days I had luck with Susano EX and Lakshmi EX... but with Zurvan EX was the hell. Even party leaders demanding high DPS, skip soar, etc, etc, etc. But you can see SOAR and you can see their aggro metter.... epic low... then even they fail some mechanich, and complain about "hey guys... why we aren't skipping soar?". So good ppl see that, leave party or just disband to avoid say anything about what parsing is saying.
So. What is more toxic? In a farm party say to one player "you can't stay here, because you aren't pulling enough dps from your job for this party finder objetives" or perform like a bad player with your job, complain about party "hey... we aren't SKIP SOAR... is this a farm?" -> leave -> disband. So good players going again to look for another party... and over and over and over, just to find more people who joins farms looking for a carry to have the chance to loot the bird. Another option SE is just adjust roll result by player performance... by the way that best player will have more chances of get a higher number at roll than worse players.
