Assumption, without proof, that is, interestingly enough, very difficult to prove.
How does one prove a (subjectively) observed pattern leads/is caused by a specific intent?
That would be like me being able to prove you come to the forums to argue with people simply for the sake of arguing, instead of to discuss.
I cannot hammer this point enough. Might does not make right. Pretend that they said “Hey I actually do key level X over time period Y, therefore other people should defer to me”. X and Y being “arbitrarily impressive” enough to create a perceived “point”
It would still be a logical fallacy. Do not do yourself the disservice of defending a “might makes right” adjacent position. It is not worth it.
I will not assign emotions to your, again, dry contextless text message in, of all things, a public general video game forum. Feel free to continue assigning emotions to my text, if that helps discussion.
To bring this all back on topic however, Blizz has introduced a new system that should in theory help with early leavers in M+. but is wide open to intentional internet disconnects. Others have preposed a “common sense” check to see if someone disconnects too much over whatever data-determined baseline is set, and I think that would be a good addition.
