But my games are not much different than yours.
Yes teams are better coordinated, supports buy support items, gankers gank timely, & most know what to do with their hero & line up, etc... BUT:
1. Still fvckton of rage, intentional feeding, all chat abuse, AFKing, & abandoning. Sure, it's lot less than low level, but it happens on DAILY BASIS. It's still a pub game and there are plenty of rages to go around. This isn't some magical gentlemen's paradise.
2. Some still don't know how to play their hero- still buys not-as-efficient items, etc. "MY ITEM CHOICE IS BETTER THAN YOURS" is rampant at all skill levels. One of the last games, I played, I still saw Tiny that made Vlad as first item. Holy fvck, what is he doing at this level?
3. Snowballing & super one sided games exist. Why wouldn't they? People give up early, rage afk, etc.
Again, this isn't some gentleman's paradise where everyone plays with a different mentality. Sure, it is notably better (esp when I smurf), people are calmer, etc. But it's still not much different than ANY pubs and ALL levels.
You should play Captain's Mode if you want to take it seriously.
