In a genre of gaming where the first word is "roleplaying", its a bit humorous that almost no one actually roleplays. Seriously when's the last time you saw a character act like there supposed to. For instance in LOTR lore we know that elves and dwarfs are not very fond of each other in, however in the actual game dwarfs and elves regularly quest together and are even in the same guilds. Once in a while you can find a elf, dwarf or hobbit in character, but after a joke or two the player would go right back to normal breaking out of character.

The obvious answer here is that most people don't actually want to roleplay. Sure being a elf hunter with a mean bow shot is one thing, but who wants to go around talking like a Legolas or not joining a quest group because theres a dwarf in it. Hell its hard enough finding full groups for raids and quest without discriminating dwafts. Also think about what you type when your chatting. If your seeking a group for a quest you probably type somethink like "LFG - quest name". If I had to write a long winded sentence in the style of LOTR, I'd never get anywhere.

With that said, I do enjoy running into people that actively roleplay. It brings the game more to life and it's actually fun to be around them. While I don't actively roleplay myself, if I run into someone that is, I try to get into it also. It's quite fun once in a while, you should try it.
