I have noticed in general Titan players are nice decent assholes who aren't afraid to take people down a few levels. They are very aggressive in crucible and tend to get themselves into tight situations in PvE. Hunters are normally pretty silent and secluded people or know it alls. Seeming more like a silent mercenary type than a guns-a-blazing type destiny tried to make. Preffering to keep a good distance from people, with guns and friendships. I am always asking "what's in it for me?" whenever someone sends me an invite. Warlocks are pretty arrogant people who are more a know it all than hunters in general. They seem to be fire team leaders more often than not. And not always but they do tend to condescend everyone. But they have some pretty good humor, even though more often than not dark.
