please try to read what im saying to you with a calm and soothing tone of voice.
first of all calm down and release your rant ok?
second its our hobby and we play it during our spare time for fun so the amount of effort to it could be minimal cause again it is just a game.
that being said i do expect that at a proper level of content that does require certain amount of effort like raids,savages and extremes there should be a certain level of caring.
dungeons and normal trials are fairly low level of effort needed to clear them but i think we can agree there's minimal level and there is absolute 0 effort.
i believe your a person who will see a person under performing/making mistakes will offer him help and advice to improve him and make the gaming experience funner to him and everyone but if we do stumble upon a player that doesn't do anything on purpose(a.k.a leecher) you can always kick him from the party and if not we can always leave and join a different one with the ability to report them as well for ruining the experience.
i believe the OP is probably referring to those who care about big damage numbers and will first stomp at people and laugh at them cause they deemed them worthless because their numbers are a bit lower.
now i am sure most of the community(at least most people i met during my runs) aren't like that and probably used a parser during their runs to just improve themselves but as you mention the thread "share a DF story" and the venting going on does give the expression that those with parser judge and then laugh/dismiss you behind your back after the run was over which is essentially toxic.
as for my view on the point of this thread, i understand the OP point of view since i saw people complain not about the gameplay or mechanics of a job but rather about how much numbers the job does that the discussion of it reaches a point that on borderline obsession with it.
the only one who should care about a damage numbers professionally are DPS classes cause damage is their main thing to do and any discrepancy on it especially a wide gap leads to banning their jobs at parties for higher tier content.
the point of the OP ,i believe he is referring to those people who started taking those parser numbers to a level that it becomes worship and instead of using it to self improve, they start to use it as excuses or as the sole measurement of people and more importantly job and worse roles when that is simply not true(like you said your clemancy saved your party which is more important then damage).
i mean there's a thread about why tanks damage don't reach dps class damage levels, which their complain is seeing those numbers makes them feel bad for playing their role(which i find comparing between roles is really irrelevant) and that its ruining their enjoyment of the role which making you ask yourself why they do it then?
