Shyvana's W is somewhat of an anomoly itself, and suffers from the same problem this champion would - does marginal to no damage against any champion that is not building glass cannon. Which is fine, because towards the end of the game you use it largely for the movement speed and for pushing lanes.

Except for the ult, the base damages are fairly lacklustre. She will be strong if she comes out of lane ahead while people haven't itemized any MR, but just one or two MR items largely negates the threat of her abilities. Plus there is a fairly big incentive for her to build attack speed over AD, since her passive and E are effectively on-attack abilities. With the exception of her Ult with that massive slow and the snare from W, I can't see me ever bothering with any of her abilities as a marksman since I will be kiting tanks and bruisers all day.

Really, I just don't see the rationale behind making her abilities deal magic damage.
