So obviously Riot is aware of it. You think that a company as large and successful as they have been has NO IDEA how to run their game? Yeah they mess up sometimes, but it's not like they see suggestions and think "Yeah it's just Reddit anything they say we won't listen to." They've actually incorporated a lot of ideas from the community, as well as some from other MOBAs.
There is no way of dealing with legitimate DC's.
Okay how do you propose to figure out what a "legitimate" DC is? What if someone loses power halfway through the game or maybe during load screen? Okay yeah that's legit. What if someone just unplugs their router during load screen to force a reset because they didn't like the comp? How do you propose to tell the difference. Yeah one MOBA does it, but LoL is SOOOO much bigger than DOTA. The average age of LOL players is significantly lower than DOTA players. The communities aren't the same no matter how hard you hope they are. If you want more discussion about that topic then do like I said and actually read the dozens of front page posts about the exact same topic.
If you're experiencing 66% of games with DCs then either it's something YOU'RE doing to cause them, or you're the absolutely unluckiest person in the world. I can tell you that in my last 20 games I had ONE DC from the start, and maybe 1-2 more in the 20 that DCed for more than a minute during the course of the game. If everyone experienced a 66% DC rate then yeah the community would be up in arms. Either you're doing something to skew the results with how you act in champ select or you're greatly exaggerating your results.
Do you have proof of your 2/3 DC rate? If it is in fact true (which it could be), can you not understand that sometimes bad luck happens? If the servers are having issues then you're much more likely to see people having connection issues during that period of time, but over the course of a month there's no way you're getting DCs that much.
Your arguments just don't make sense. Don't act like you know everything there is to know about running a game. Don't act like just because one company can do it it would be easy for another company to (especially when the number of players is SOOO different). You're just ranting because you're upset about being chat restricted or punished over and over. You admit to being toxic (whether or not you see it as toxic is irrelevant, but you admit to saying things to people, especially in post game, that is seen by some - including Riot - as toxic). Why are you so shocked that you keep getting banned? Instead of ranting just fix your attitude.
