Literally any time you unlock a spell from a pack its for the wrong school. Why can't you simply just transfer the spell to your other characters. I unlocked a balance spell on my fire wizard account and its very upsetting that my balance wizard can't use it
I think that they are making future spells very safe from these issues. Spellements to unlock, like in the case of the new Celestian spells, allow this to become a non-issue.
I understand being frustrated that you can't transfer Lore spells (from packs or otherwise) across your characters, but the goal is that they will be difficult to acquire and valuable to use.
I, personally, see no reason to deviate from the status quo at this point, especially with how many spells would likely become available to lower level wizards through exploits in such a system.
This is for sure needed. The spells are so rare as it is and I am not gonna try to buy packs apon packs on 8 wizards. I am not that dumb. I have almost 7-9 spells (lost count) from different schools. Whether it was from a pack, or a rare drop. We need these to be transferred somehow. I do not need a myth heal on my life, or winter moon. It needs to be done.
