Your opinion on mana eggs is noted, but I do not feel the same way about it as you do. To me it cheapens the experience and ruins the individuality of each character. You claim it is more strategic to have each egg to be unique and reside with a particular individual, but in the first Grandia, each character had their own unique set of spells that made one better for healing, another better at offensive spells, etc. Maybe your point is that potentially each character in Grandia could have healing spells, but there aren't enough mana eggs in Grandia to give each character the four realms. So in strategical practice, it amounts to a similar thing, but Grandia keeps individuality.
