Crazy Awesome: It is the general consensus that if Guild Wars 2 doesn't suck, it will be this.
Crowning Moment Of Funny: What do paragons and drunkards have in common? They both run around with no pants, shouting at people!
Dark Is Not Evil: Neither the Necromancers or their divine patron, Grenth, is at all evil, and in Grenth's case, he's the usurper of a definitely corrupt deity, and he himself has no power over death, being advertised rather as a god of justice. Though, during Wintersday, Grenth can be kind of a dick.
Ritualists as well. Ritualists cast spells by binding angry spirits with ethereal chains or channeling the raw anger of dead souls, but much like Necromancers, can be perfectly heroic people. Heck, Master Togo is a Ritualist, and he's arguably the nicest guy in the entire Factions campaign!
Deader Than Dead: Banned players. When a person's account is banned, they are visited by Dhuum, old god of death, specifically of death eternal. He appears before them and, with a unique skill called "Vengeance Is Ours", cuts them down with his scythe, sets them on fire, and transports their soul to a prison in the underworld. As the skill used to do this says, "Ressurrection skills won't help you. Your account is banned." Let it never be said that Arena Net doesn't have a sense of style when it comes to banning people.
Death Mountain: The Ring of Fire Islands. Oddly, the extreme heat doesn't seem to bother anyone.
Somehow, Mhenlo, the pleasant, upstanding, and good-hearted monk. Even he doesn't seem to understand why he's so pimptastic.
This really gets on Cynn's nerves in Factions, where everywhere Mhenlo goes he seems to run into another attractive young woman he knew way back when he was studying under Master Togo in the old days.
some of these are hard to understand if you haven't played the game but the others are hilarious w/out the knowledge of the game.
