Man, you trial-hates need to chill. You can't blame all the hunters, especially the ones who don't play Nighstalkers in PvP. Titans and even Warlocks have had PvP exploits too, just not on a grand scale to actually close down a PvP event. Besides, it's technically Bungie's fault for not putting enough QA into the game to begin with. Had they done more play tests, they probably would have found this exploit and fixed it.
