Which is why you limit the power multiplier and defense penalty to prevent the user from turning into a sock puppet.

A semblance is, as we have said several times, a singular power. A shield that damages nearby entities is one power, and an attack/defense tradeoff is another completly independant power. Each of these two aspects is a semblance on its own, and combining them goes against the few set rules we go by.
