Do you think it is worthwhile to be able to views someone's "reputation" in WoW. How I envision it works is like this, in 5 man dungeons you would have the option to "like" someone. You would use this because they were decent people inside this 5 man, they were polite, skilled whatever you liked about them.
You would have the option to right click their name and choose "like". You could only do this within 5 man dungeons. People might even get achievements for getting certain amounts of likes. You could not give "dislikes". Anyone could view the "likes" on anyone within WoW at any time.
Would this matter to anyone? What are the downsides or upsides to it?
Edit * - Besides achievements for amount of likes, you could possibly get a title and/or a special mount if you get a certain amount. Maybe at 25 likes you get a title, 100 likes you get a mount. 200 likes you get a better title and/or mount. Etc etc
