That’s not enough, still. It should directly affect the rank too.

I disagree. I think they made the right call to make behaviour score and rank seperate.

Because rank is everything to those toxic people, it is the only thing that drives their toxicity.

Not true, I play a lot of unranked and there are many toxic players there as well.

But they made a mistake by making the rank public, because now the players are no longer playing for fun, they are playing to raise their rank

Same as before, people play to win regardless of there being a visible rank or not. The game is competetive either way, and competetive games attracts toxic people.

This is just a flaw of mobas that no ones learned to really fix yet

A flaw of humanity really. But unlike Riot, Valve has and still are taking action against toxicity in DotA 2, for example with their behaviour score system.

• Reports for toxic chat, toxic voice, and/or greifing will lower behaviour score.

• Matchmaking considers this score, putting toxic people in matches together.

• If a player’s behaviour score is too low they will automatically be muted.

• Typing slurs in chat lowers behaviour score, and too many will mute the player for the rest of the match.

• On the match found pop-up, it tells you if the behaviour score is differing between the players. You can then either press confirm or queue again to find a better match.

• At the end of a match you can dislike players, which will lessen then chance of meeting that player again. You can also press avoid on a player, making it impossible to be matched on team with that player again.

There’s more to it, but that’s the gist of it. Still a toxic game but at least 10 times less than LoL.
