Problem is, 250K is an odd number. If you're at 3750K and wanted to buy a new starship line, you'd regret ever getting auto-frd nodes or something like that, since knowledge is mostly used in bulk, thousands per deal.
Getting rid of 250 K prices by either nulling them or upping to 500 isn't that much of a problem, it's optimization in K resource handling, imo. And for the record, I don't use rally posts at all, I'd rather keep the control to myself.
Huh. So apparently this post had two pages, bah.
