I mean this in a nice way, but level 5 is nearly nothing. hell, people say that leveling to 50 is just practice for the real game.

nothing is going to change much at level 10.

I have no idea what you mean by getting attacked by NPC's

finding groups, active stable guilds and chats are nothing to do with level however. You can do all of that without even getting past level 1. By the sounds of it you need to go out, find a good, medium sized FC, talk and ask questions and fall in love with the game and people. Out of all the complaints I've heard from this game, I don't think I've ever heard anti-social being one xD
