I think almost all my best friends of nowadays were met playing this game.
In fact i have met better people ingame than the ones i met IRL.
We used to have meetups and i managed to meet one girl and date her, even though she just turned out to be a real royalty of a bitch in the end (*S).
Nowadays i lost the patience to meet new people and i have been a bit of a antisocial (only doing world PvP against other level 100's) but i think in Legion i will try to meet new people and start playing with a Guild with players of my country again.
