In my opinion players created many dedicated accounts for prototyping. If you want this prototypers carebear for research one more time: this prototyper will be useless. Why? Because whole corp worked for few dedicated accounts, and worked really much. And now you want to put corporations into situation when they must work for research what will erase itself after some time/ct creation?

All fine with curent system: after prototyper gained knowlege he need huge ammount of mats to make this prototype. All research depends of kernels you using, and people fine with it: want a best tech - do farming. Gained desired tech: now you can sink mats to make proto.

Now its too late to make a brand new experiment with core functionality. This changes should happened during beta-test, not after game release.

Im highly sure that current prototypers will drop playing if devs will implement sort of "erasing of KB". Prototypers now had a problem to get a mats for prototypes, and you proposing to add new butthurt for kernels.

New "experiments": new unsubbing wave.
