Even if you have a few spare your left in limbo as to when you use them. What if your next two powerful drops in the same slot but you infused on the first drop. It's a waste. Until your drops are at the power cap it's a flawed system I believe.
And you can rarely use them to actually master work anything. I hope this comes across as constructive criticism as that's my intention.

I think your missing the point. I don’t have a problem getting cores, I know how to properly use cores, and not waste them. But the infusion system in my opinion is not good. Getting cores from spider is often a waist of time. The materials farm is a work around that is tedious and boring. It proves the system doesn’t work.
