Why do you need to find balance? if you want a solo RPG go play one, they are a dime a dozen. MMO's take years to develop and they are expensive to develop (SWTOR remains one of the most expensive games ever to develop). Thus, the developers depend on having the game run for years in order for the game to be profitable. How does a game survive years? CONTENT. Content with replay ability. Furthermore, mmo's have never been popular for their dynamic combat systems. Game's like dark souls and bloodborn have a much more engaging combat experience. Why do people choose MMO's over other great games like the ones mentiond above? Content and to be social.
