It’s like asking “Why did you choose to do your homework?” The teacher assigns it and the student does it for the grade, not because they are necessarily interested in the subject.
We’ve had Kuzco on the prize wall for less than a week.
Most of us are still earning his chips from prize wall.
Most of us probably stopped promoting him at y0 because that’s all that’s required of the prize wall.
Most of us probably haven’t raised his level or skills to max because you don’t have to in order to complete prize wall.
Most of us haven’t even done his friendship campaign let alone decided which disk is better. Then we’ll just look to what others suggest.
Most of us… will leave him at the bare minimum to complete prize wall. Then we’ll wait and see if he becomes popular/meta . Then maybe we’ll level him up, but there’s no rush as chips for raising red skill are months away (without paying real $$).
This is how you’ve trained us. Completing prize wall quests are beneficial, even if you don’t care about the new hero, so we’ll do them. Doesn’t mean we love the hero. We’ll unlock the hero, complete quests, and then wait. Because just as many of those new heroes are crap as are great and resources are too scarce to waste on a dud.
