This is one I've heard of many times before, the whole "Well I'm telling them what they should do, and they just dont LISTEN" reason. But there's one question I always ask at hearing that: How does the person you're saying stuff to know that you know what you're doing? How can they know that your advice is any good? Particularly when you've got 10 bazillion idiots that will of course be giving them opposite advice in other matches, and those people will ALSO think they are right. That's one of the things about this genre: Half of it is people arguing over which set of stats are the best, which strategy is the best, which build is the best, and as a whole, nobody ever agrees. Just because someone SAYS you have to do such and such, doesnt mean it's actually true/correct. I learned that one from fighting games... everyone in that community always rambling on about frame data and which combo you HAVE to do and blah blah blah, except that you dont *have* to do any of it. *I* dont, and as a rule, I'm the one usually winning against those that think that way. They say all sorts of things, and use all these technical terms, and explain things in such detail, but really, there's different approaches that one can take to games like that, though good luck getting that through anyone's thick head.
That's the sort of logic I usually go with, going into a game like this. Just because someone is telling me "GO DO THIS!!!" doesnt mean that going and doing that is actually a good idea. Too many times in other games that I've played previous to this one, I'd listen to advice given.... only to have it cause nothing but trouble. So I've found that the best way I can learn (for this genre, anyway), is reading guides, and watching videos. Just listening to totally random people that may or may not know what they're talking about is just going to confuse me.... so I dont.
But there's other reasons, too. In some cases you might run into someone that's just tired of listening to other people, because of having experienced so much toxicity as it is. Maybe they either mute everyone, or just dont really glance down at the chat anymore at that point. And it could be something outside of the game, too. Maybe they've had a bad day, or are having pain or something, and are simply distracted, and not really playing their best. Stuff like that can happen for anyone, and of course it sure doesnt mean they need to be yelled at.
I forget where I was going with this.
