PvEvP games are always doomed to fail because they always attract the worst scum playerbase. These players spend their time hunting and griefing other players to get high level gear quickly. Then the "wealth" gap becomes so huge that new players quit, and the scum players complain about losing players. They don't want to fight each other because they might lose, they just want to bully new players. You see it happen all the time, these games have a moderately high initial player count, which falls to less than half that number in less than a month.

This is why Marathon being a PvEvP extraction shooter shows how truly braindead Bungie has become. Reviving a cool IP just for it to be dead to nearly everyone before it even releases.
