i dont create bad items, i create items make you think about how you play and change how you might play. i have destroyed bosses with a well placed lemon mishap, it might be thought of as the worst item you can get, but its not useless, no item is useless but some give you the challenge of finding ways to use them to their maximum potential.
im positive there will be items in rebirth people think are bad, but they will find uses for them.
but yes for each OP item i try to make a lower powered item counterpart
