I dont really think I read carefully enough to comment on the rest, but I realy liked your idea on the riftwalk changes. Making Kassadin think a bit as to when he can use riftwalk and onto what really changes his playstyle a bit, and although he his supposed to be (ideally) a reeeally mobile dude, this still gives him his mobility while requiring him to use it a bit more carefully because flux will not regenerate as quickly as his mana anymore, and the range drops with consecutive casts.

If there was one thing I would change, though it would be the damage on the later rifts- i think the dmagaes are a bit too high- his riftwalk really is supposed to be mainly a utility spell, not a damage spell.
