(Do you think every single changeling is going to be able to acquire friends and lovers to feed on?

Noci doesn't. And, with his current power, he could at least convince the ones in his pack not to.

Yes but how do you absorb love from creatures that don't love you? They may try to take them prisoner but ponies wll resist and thus need to be put down.
