Used to be the best MOBA in terms of mechanisms and balancing, until the developer decided to do nothing about the report system that can easily be abused. If you're a team player and focus on objectives, but didn't have a high K/D/A, you'll be reported by your toxic teammate(s) for "Active Feeding" or "Passive Behavior", which is also validated by the system, and banned. The developer didn't want to kick out those toxic ones, possibly out of concern of affecting the size of the player base. However, this only drives away all the team-oriented players, leaving the toxic ones only. PS: oddly though, the Chinese equivalent of AoV, namely KoG, has a report system that's much more intelligent and cannot be abused as easily.
