I had talked to my brother after almost 4 years, and we had also talked about how character classes compared to RL stereotypes. So here's what we came up with. BTW, I'm going by the capabilities and lore of the classes. I am not going by how people play the classes or going by the players of WoW.
Death Knights - Emotionally disturbed
Druids - Environmentalist hippies
Hunters - Experts at surviving outdoors
Mages - Very smart and rely on wits to get by in life
Monk - I haven't really figured that one out yet
Paladins - Seemingly all around perfect physically and mentally
Priests - They do too much for others and not enough for themselves. In other words, they are too nice.
Rogues - Silent, but their presence alone gets them respect.
Shaman - Full of great advice they have acquired from experience to offer to people younger than them
Warlocks - Mainly goths
Warriors - Very strong, but also lack in wits
EDIT: You people totally missed the point of this thread. GG
