Re: Beating a Charger
If he's getting away then he's got you beat - that's your chance to get him. Even if you stick yourself in a corner, if he can get away far enough just to charge you again, it's already over. Lower levels makes it more difficult as movement speed makes a huge difference, and aside from the sorcs no one has teleport. Charge will allow him a superior advantage - unless he makes some serious mistakes or some teamwork is involved (or you switch to a higher more powerful character) don't expect to win.
While I always frown upon pkers (I prefer pvp combat when I'm looking for it) I honestly wouldn't be too concerned. Pkers are geared with one goal in mind, and at the lower levels its going to be very hard to handle if your build isn't pvp oriented to begin with.
I honestly wouldn't worry about pkers if your goal is pvm, they'll come around from time to time but not worth adjusting your build for pvp, since you would have to.
As far as pkers go, most don't hold up well in a fair fight so they pick on the weak. A few skilled duelers do get bored and go for some pk action from time to time, but really the majority don't hold up well in "fair" fights.
