The Case for More Key Lockers
1) There are more portals now. Thus, more keys needed if you want to be prepared for dynamic fielding.
2) We've been nominating for 5 years. It's heartbreaking to have to delete the key of something I've created because it isn't practical to keep them all. (I have 364 portals created, with 16 waiting decision, and many more to nominate. Many have more than me.)
3) Qcap removal: If I hack a place that MAY be useful in the future, I'll need to hack 20+ keys - and keep them, maybe years, until they come in handy. Formerly, I could put 5 keys in a quantum and consider an op as they grow.
How about allow 8 Key Lockers (8 is a big number in Ingress), and +1 for each recursion?
