So the purpose is to have fun? Oh my, all this time and I thought it was a wargame.
If you are a good target you'll be attacked.
You have no means to threaten the people that consider attacking you, therefore you are a juicy target.
If you get some offence that you can hit back with, not so good target.
If you help people in the kd, so that they can hit those that hit you, not so good target.
If you explore, with only def specs and forts and come running to this forum to have the creators limit the possibilities for attacking others; good target, wuzz and playing the wrong game.
If you want safe fun where you can do things at your own pace I reccomend something a little less dangerous than an online wargame, something like.. Sims?
