the blue parts really depends on the gameplay and necessity of blue for a certain champion. yes, udyr doesnt need blue. but it does make it possible to permanently keep up bear or tiger stance, which greatly increases chase and tower dropping. another example is ezreal, who can keep up his passive infinitely through blue and can get his ult on a CD of around 35seconds with it in addition to Q hits.

i'm making these examples to show that some champions, who arent that mana hungry and who arent per definition mages, could want blue.
