The Lanun have four cities, which isn't that bad. Land doesn't mean anything either - plus, the actual amount they control is no greater than anyone else, it just looks that way because it's all spread out.
Now, on the rest of it you do have a point. However, I don't think that the Lanun have influence in the Amurite or Calabim nations anymore, although I may be wrong. The smuggling bit should definately be nixed, I agree there.
Granted, I'm not exactly unbiased, but I don't see the disparity as being as great as you implied. Still, Jopa did mention he might be working on a little more yet, and if he changes the situation more I don't mind at all.
