Believe me. I have done the things you have suggested too, Mithron. In most cases, it is usually successful as long as you are respectful to the others. I am trying to account for those other few instances where a true brick wall is hit. Some of my points came from experience when I was in the Warcraft game. I have to learn the hard way that not everyone will like me and some will decide to be my enemy with no way for me to control it. But as you said, we still tried our best to help them using our voice. I can agree that the help may be taken indirectly by other bystanders.

My second point may sound moot to you, but I have honest to god encountered players who will not accept help. Period. A few actually dug their heels down to the ground, called me stupid for asking if he used some cooldowns to preserve his mana (Healer Priest Class) and then said he refuses to listen unless I am in Germany sitting by his desk >.> Umm, right ... he wants to pay for my flight from Canada then? He would rather blame the person trying to help him while he complained about going oom way faster than me at the same time. It was also an expansion change from Wrath to Cata when spamming Flash Heal started to cost way more mana and the devs wanted us to use the efficient Heal more often. We still used Flash Heal, but more so when the enemies did their versions of tank busters, if you know what I mean.

As for the third point ... I hate to break it to you, but some problem trolls are not embarrassed by exposing logic on them. Some will instead cherry pick your words for the next response or ignore your "killing blow" while recycling points that were already beaten at the start of the conversation. It's a strange fixation on always getting the last word for them even if their point is nonsense and doesn't count. In fact, they successfully do get attention rather easily for posting something nonsensical. Some posters even said it was their "last word", but the troll roped 'em in again with illogical points.

I have more such stories, but this post is starting to get big. Sometimes we need to know when to call it quits based on these points. I have been able to diffuse anger before so they were more able to listen. It's not 100% guaranteed to happen though since this is partially out of our control if the other party decides to calm down and humble themselves.
