I feel like Shyvana Should be simple.
10 Fury, it's the exact same as 10% cdr.
All have small lock outs that are impacted by the 10% technically it does do something.... albeit very VERY minor. They just have really short CD like Kassadin.
does have an ult and does not need anything special.
Is the only other champion that like Shyvana does not have a true ultimate cool down rather just a timeout from all his abilities. Reducing his lock out on all his abilities could work.
A bit Ironic that
is the only champion that get's literally 0 benefit from the Dragon lol except her nerfed passive of course.
