This does not mean we don't try. They keep releasing these videos and cinematics, but have they released educational videos for this kind of things? I mean so long as they have a disclaimer that tells people that they attempt some stuff at their own fruition, then they could inform about proper maintenance, tips on setting up mouse sensitivity, and the dangers of over-exerting their bandwidth. I'm not saying it is something that can be outright fixed, but a more accurate ping system and the ability to see teammates pings would help as some people complain about ping all the time and most likely have 5ms ping.
Also, I've noticed some people having slow load times even with the rework of their file systems, which leads me to believe that these people don't defragment their drives. Some people lag graphically too which could be settings that are too much for them, or they haven't properly updated their computer.
Long story short, they can't fix it, but they can at least take some form of prevention to help it along. like that one video on toxicity, if they can do that but with tips on communications, how to deal with trolling, maintaining one's system, and such. It would be better even if just a little portion.
even if they don't create some special matchmaking for lagging people, they should at least give proper latency feedback, some form of educating their players, and take a step back and look at how each variable affects players.
instead of some dude spamming "I'm lagging!OMG!CMONRITOPLS" he could have an accurate latency that is shown to his team and they could go "oh @#$% dude your ping, how bout you switch with the jungle or (insert lane already doing okay) and we'll pick up the slack".
i may be repeating my self I'm not entirely sure. also I can't tell if this is wording my point right, but if you make a game and you create this huge community who follow your videos, buy your skins, and support you. wouldn't it be just for you to let your presence be known and attempt to help them by also educating them with a fun spin on it?
faster load times, less lag, more awareness that the servers, your internet, and the game itself isn't the only factor?
