Kill Stealing

... But really, is it KSing now just because I am too high a lvl to be "training" in an area but take the spot anyway?

Heck no! I think they just didn't understand the concept.

You were already being nicer than many people, who would've just continued whatever they were doing because they were there first. However, that map is big enough for at least four people to share, at the levels of actually training there, so it sounds a bit greedy of them to want it all to themselves. You'd actually be increasing the spawn due to your faster killing rate, anyway, which helps them.

You have the same philosophy as I do, BTW. If I'm hunting or training somewhere and don't need the whole map, if someone else comes in I'm quite willing to split it. That often makes my life easier.
