Some people hate because they're loser hipsters who hate everything, even the shit they like. Other people hate because they're loser trolls who need attention from strangers online because they don't get any attention in real life. Other people hate because they're entitled kids who are used to tantrums getting them what they want. But then there's other people. Other people who like the game (maybe even love the game), but are getting fed up with the direction the game is going in. I personally think this game's hate will continue to increase the more Bungie focuses on PVP and practically ignores PVE.
