I've said it before, I'll say it again => hunterkits should only have been made available for 100+
As such, it forces everyone lower than that to be actually active. To find parties and to do actions together. This way, they also learn to know new people and expand their friend list. Once they do hit lvl 100+, they know enough people to continue the parties with hunterkits, know enough people to do dungeons with and will automatically be at least chat-active at some times just to talk to acquaintances.
At the moment, however, one just goes afk hk from lvl 15 until eternity and they have nobody to rely on, to talk to or to do stuff with and thus they find the game boring.
