heroes of slowing and earth magic

It has long been a well-known (though niche) fact that the magic system needs further refinement. In World Tree, for example, Town Portal was removed from Earth magic (and moved to Fire). And Slow was on level 2 (I would move it to level 3). But in Shades of Darkness, it's clear that nothing like that will ever happen. And judging by all appearances, Heroes of Might and Magic VII won't see such changes either. At least, the current situation is definitely that. So, we just have to play as it is. There's not much else to play.
