Being ignorant on T10+, and speaking specifically on my experience as a SMN only player who is on T9, I have to wonder what am I doing wrong that MP has never been an issue for me. Even on burst fights like T8, I have never had issues with mana, especially having the need to pop an emergency pot. My biggest issues with Mana come with Rezzing a down fighter. That being said, is the curve that much greater for T10?
