you know what time it is
Arcane
Heroes scale into late game with items though, got active abilities and allow you to use cards from the same color on the lane they are present, so they are not just stat sticks. Separating most of their abilities into "signature cards" (or whatever they are called) is a pretty elegant solution to their power curve, otherwise shit would play out like HOMM4 (weird comparison, but it fits in this case), with heroes smacking each other while creatures and spells become almost completely irrelevant after a certain point.
