I have no clue which element works better against another, no which type of hero works against another. Is there a guide to explain how the game works?
There is indeed a “guide” to the element system, I will provide it as an image attachment.
As for the hero type system, I don’t think there is any guide, but you can get a rough idea like, supports are squishy and assassins deal burst damage, therefore assassins counter supports, or something along those lines.
I know this reply is very, very, very late, but I will post it regardless since new players might come here looking for answers.
