Fervor should give AD AND AP per stack

Yeah, because that worked sooooo well for rageblade. It absolutely opened up that item to a wide number of champions! It totally didn't just limit it to the 1-3 ranged champions that can perfectly use both stats.

It's a silly idea. If you make it that stat efficient for certain champions (Kayle), then they either have to be nerfed to fit the mastery, or the mastery has to be nerfed so that no one else ever considers using it because of how shit it is when you can't ideally use both stats. The point of this update is to make fervor fit with the actual playstyles of a larger number of champions instead of feeling like a pure on-hit option. That does not mean tying it even more strongly to an incredibly limited number of champions.

How about no. Imagine this on Cassiopeia...

NOPE

it gives bonus damage

based on stacks

That way, it's good on crit champions, but also good on hybrid on hit champs

Instead of only giving ad on pbe

Wouldn't that be abused like crazy on Kayle. You of all people don't want ranged champions in top lane.

and suddenly and became impossible to balance
