Agreed. The lower tier scrip cap should be 4k, not 2. I can understand wanting some sort of cap on currency, but 2k is annoyingly low considering how easy it can be to get scrips in bulk.

"Hm. I have 900 scrips but a master book costs 1200. Let's do some quick custom delivery turn ins." Oh wait, no, you can't. The scrip cap is so low that you can't even turn in all your deliveries at once without over capping.
