With the existence of skill injectors balancing of high power toys becomes very difficult for CCP because players can inject into using within hours in masses. See the Rorqual debacle.
My proposal to address this issue has two measures:
hard cap the usage of injectors at a threshold, for example at 100M SP (number has to be carefully decided)
Increase the skill requirements of high power tools, in order to require more than the threshold to effectively using it.
This will keep injectors valid, but gives room for rare, expensive but powerful toys to aim for. Players will be able to inject close, but only normal training will make them master in the new toys.
What do you think? Was this ever discussed before?
