What is the point of Everstone?

Question

Can't you just press "B" to stop the evolution?

Answer 1

The point is to:
1. Not repeatedly see: What? __ is evolving!
2. Not having to press B at every Level.
3. Save time.

Also, it can be used in breeding to have a 50% chance to pass down the mother's nature.

Comments

Still seems a bit unnesscary though...
