As of right now, noone uses the Psi Shield.
My idea is to make this ppu spell an apu spell.
Why? PPUs dont need it, because its just another mana drain. Apus could really really use some kind of working defense against mobs.
It could maybe even give an apu a chance in duels, while i still think that the psi shield would be useless in opfights and group pvp.
I really think turning Psi Shield from ppu to apu will be the perfect solution for a solo apu and for easier leveling
