Should I bother purchasing masteries before the mastery update?
I have been planning to save up units and purchase the masteries that I have not unlocked yet, like despair, deep wounds, assassin etc. However I heard there is going to be an update for the masteries, so would it be a good idea to save the units for when the update happens? Or should I just unlock whats available now. Also any idea how big the update will be or when?
