I was responding to TheDevil, hence the little respond image in my message.
As for what you said, of course I recognize that looming problem, but that problem and this one are separate issues entirely.
And for the record, they said they have a fix coming to help players, free of charge, to dump their massive pool of items into new storage kits:
That actually should fully address your concerns.
Now with that aside, back to the topic at hand. What's the deal with the power kits that drop from item boxes? Why are they possible to be upgraded if upgrading them is done at a 9/10th loss rate of boosting power, and costs additional gold to do so?
