Rank 1: You have a 50% chance to heal your pet for 50% of the amount of spell damage done by you.

Rank 2: You have a 100% chance to heal your pet for 30% of the amount of spell damage done by you.


Is this how it was intended to be or is this a bug? If this is intended, why is rank 1 50% and rank 2 30%?

Sorry if this was asked/answered already I couldn't find anything about it.
