Now that we are close to reach level 130, we should get to choose our secondary school, without the need of a mastery amulet. We graduated Ravenwood, so it just make sense to continue our studies with one of the teachers in the Arcanum. This would add more diversity to our decks, and more possible combos in both PVE and PVP. Loremaster shouldn't be the only creature in the Spiral to use all kinds of spells!
I also want the trainers in arcanum to teach spells levels 110 - 160, kind of like how ravenwood teaches 1 - 42, then each spell after that is a quest.
