Personally I think that her skills should have a bit more variety in mana costs to make her passive a bit more interesting. With nunu's passive its really important to use iceblast or absolute zero over consume or blood boil, you save almost double the mana.

With Lissandra no matter what you use you're only saving ~100, they could easily implement the same thing via flat mana regen. Eg while you have an enemy slowed you gain 5 mana per 10, this effect stacks with each enemy slowed. This would make her passive fit her kit much better imo, however it would decrease her potency in the laning phase (which is the real up side to the current passive).
