What can we even talk about when you almost always play at 160%... on maximum difficulty, the development tactics and everything else are different from playing on easier difficulties, and what you wrote above about a bunch of main heroes with powers running in different directions already in the first weeks is just NONSENSE!!! I repeat, play more often on maximum difficulty... and if you're already responding to someone's post, then compare it with the maximum possibilities... otherwise, there really are misunderstandings and disagreements in opinions!
In most tournaments, everyone plays "like adults":) that is, at the maximum possible level... so you need to get used to playing like that from the very beginning... and it will be easier on easier difficulties later.
