Understood. And whatever you can do to blunt the blow of criticism, do your best to try it. The less people feel defensive (especially when they're struggling), the more receptive they will be to altering their positioning or style of play. Like last night I was struggling as a carry against a team with 4 blink dagger initiators. Instead of,
"Yo wtf guys. FFS...counter-initiate on them goddamnit. We're gonna lose. WTF is our Venge doing"
my approach was,
"Hey guys, they're looking for opportunities to initiate on me. I'm gonna try to hang back, but be ready if they try to do the same thing again. Venge, be ready to swap me out next time if possible."
or something along those lines.
Whether it's about improving positioning or items or skill builds, I generally get, "ok" as opposed to "stfu". There will be some of those too and you can't do anything about that...but as they say, it is often possible to make lemonade if you add enough sugar to the mix.
Embody the change you want to see in the community and you'll often have better experiences than most. If something constructive can't be said, don't say anything until there is something constructive that can be added.
