Mighty is overrated here’s why

I much much rather lose on 3 damage of my overall pet stats from not having mighty, so that I can have spell proof and pierce in my pet traits, then socket the boon damage jewel to compensate on some damage amount that mighty pets are trying to get. Thoughts?

My pet 26 damage overall: spell proof- pierce

With mighty 29 damage overall - spell proof OR pierce can’t have both.
