big KD's farm small ones

i think its kinda obvious that a poorly managed 500k nw prov is still stronger than a well managed 350k nw prov no matter what.
the correct answer is because people want free land.

this is not true. you can run a smaller prov that will discourage a competent attacker from hitting you - even if you cant retal him, simply because you can retal his kdmates.
