Should Tabi also reduce physical spell damage

For now, the only thing tabi does is to delay the adc powerspike by another 10 minutes, while most assasins get barely affected by the damage reduction that barely applies to them. It's why the only existing ADCs now are either casters like Lucian or Guinsoo abusers.

Compared to mercury's, this item can decide entire matchups even in toplane, reducing the champiom pool significantly and is just plain boring to play against.
