3v3 is UNPLAYABLE due to BOTTERS

Why are botters still an issue? I've not been able to play 3v3 in over a year due to every single game being nothing but botters!!!! You PERMA banned my main account I've had for over 5 years due to language (its fine I broke the rules I accept responsibility).... but you let botters absolutely RUIN the game. I understand you can't catch them all, but its called anti-cheat detection, which you clearly do not have (if you do, it needs serious reworking). You should be devoting ALL of your developers to solving this issue over adding new champs balancing gameplay, etc.... this needs to be number 1 priority, and so far I don't even think anything is being done to counter it. I'm stuck playing 5v5 which I enjoy, but I like 3v3 better and I haven't been able to play it for over a year now. Its one thing if it was an occasional bot I run into... but I just played five 3v3 matches today, and each one, my entire team was bots... only one game I played had a human player, and he was on the opposing team. If this is how you are going to handle this issue, I will surely stop supporting/playing this game. Do something to fix it, or I'm out for good!
