i don't think ff14 attracts the same kind of players as wildstar, though.
obviously there will always be many trolls and jerks in every online game, but i'm hoping wildstar's focus on humor and somewhat cartoony visuals will have less of them.
plus the devs are trying to make boss fights challenging in a way that still makes it easy to understand what's going on just by playing, mainly of course with all the different kinds of telegraphs.
i don't remember about rift, but i had mostly good experiences with the people in swtor and gw2 too :]
