Sounds like you just lucked out on some grade A losers. The few randoms i've played with were very polite. Hunters are far from useless in end game. It's just that warlocks and titans have more going for them that they kind of over shadow hunters late game. For instance warlocks can self res in the raid making things easier during slip ups. Titans have an unbreakable shield. Hunters can one shot oracles with golden gun. Which makes the portal run phase of atheon much easier. I will say that blade dancer is pretty much useless in endgame. The invisible to res is nice. But it's very situational.
