No and no. 'Grey magick' doesn't have anything to do with 'shapeshifting' and 'boring stuff' it refers to the fact that all spells could go either way, they could be 'white' or 'black' depending on how you perceive them.
Example, you cast a love spell on your crush. Love spell is good, therefore 'white magick'. But how do you define 'harm'? If it includes forcing something against a person's will, then a love spell is in fact 'black magick' because a love spell designed to make your crush love you is overpowering their ability to choose freely what they want and will instead do what you desire.
Another example, you decide casting on someone unwilling is harmful, but you have a sick friend in the hospital, and you know you could help with a healing spell. They say they don't want any spell used on them. Do you obey their wishes, or cast anyway because you are helping them?
This is 'Grey magick' it's the realization there is almost always a moral dilemma with spells. Practically every spell could be debated as 'good' or 'evil' and it is your decision what is best.
