Or she just chose Equestria as the richest place in terms of magic due to some extreme situation, such as full-scale starvation of the hive (which can happen due to many causes).

And the usual way of changeling feeding is quite different from the full-scale assault (they are parasites, not predators. And thanks to their shape-shifting abilities, they don't need to attack and seriously harm somepony to keep themselves well-fed. Not to say a sentient parasite won't leave himself without valuable hosts - cause that means starvation and eventually death to himself).
