and the people that can handle it will only learn to do such the more they're exposed to such an environment. No amount of simulation or dummy training will adequately prepare a player for that, barring the simply fact they will potentially have the fundamentals of their class ironed out, but they still once again need to juggle both and they will only do so by being exposed to such an environment. I suppose the simple fact this isn't an entirely natural process though just goes to show some of the inherent flaws in the more casual content.
It is wrong to assume people are exclusively malicious in their feedback or criticisms, equally so it is both wrong and disingenuous to assume that nobody is exercising their 'freedom of speech' to plain and simply put harass other players. - In case it isn't made abundantly clear a player not performing of a certain benchmark does not warrant harassment.
Yes all players are equal and as such both their performance and input should be objectively examined not just tossed away. It is objectively conceited to throw away the opinions or input of others because they don't meet your arbitrary standard.
Any feedback or criticism or input should be objectively examined, and questioned, not just thrown away because "lul grey parse kill". Is feedback from a potentially subpar player going to be questionable, sure? But is it immediately invalid? Nope. Because the issue at hand isn't as simple as black and white.
No it is vain to discard that opinion exclusively on that basis. As by your own admission for a first time clear this can be for a myriad of reasons but for repeats it's less permissable, hence why I said the sole metric indicative of skill or ability should not be on the basis of a singular clear.
No it is entirely down to delivery. If your sole criticism is "You suck, stay out of savage" - Then that is more on the side of harassment than it is on the "I just gave you some good constructive criticism.". There's about as many people in this community that are overly abrasive in their 'criticisms' as to what there are players disinclined to learn and improve.
No they are equally as important, but a dead body doesn't do any DPS, whereas one alive that respected the mechanics can still continue to push out DPS, and nor does a player that dies and thus potentially causes everyone else to die. I never said nor implied that it is less important, just that it is equally as important as being able pump out DPS, and just highlighting the simple fact that foregoing some DPS to ensure that you can execute mechanics is important. If a member potentially or does perform in a subpar manner then that's fine. Grandstanding aside it's an objectively good solution to a potential problem. They can improve from thereon.
