How to improve Ivern

I enjoy playing as Ivern, i got to levle 6 with him in under a week when he came out while other players did not know how to fight against him. But now a days players doand what hurts ivern is there is not a solid build tree for him. You can build him full ap for daisy but his other spells do not get a big enough power increase to make it worth. I think the best thing for ivern is to change daisy's power increase from all ap to well everything else. Hp for hp, AD for AD, and Armor and Mr. This would allow us to build ivern tanky without it crippling daisy for not having ap. I say ad as well cause well i already put that on ivern so i can solo drakes and baron
