On the other hand LeBlanc is an exceptions because she benefits a lot from flat mana regen seals cuz she can kill other champs at lvl2.
For AP rune page i suggest MP5/lvl if u have only normal "mana" mages.
If u like to play katarina or ryze then hp/lvl are better (cuz they are not behind like other mages and they need that HP, also with Ryze u go for max Mana so you really dont need mana regen).
