Spot on. I'd take an increase of white manastones more than anything. But we all know it'll be mp, parry, evasion etc. Soul sickness and skill books are too expensive with no drops. Leveled a toon on NZ, I could not afford skill books from level 50-55.
I dont like the idea of adding felicirous sockets, that'll be more quna cost which, like you stated, is creating an imbalance. How bout just making the failed manastone break not ALL of them.
