I'm planning on buying runes (sooner of later), but I'm not really sure which to go with. I found [a guide on solomid](http://www.solomid.net/guides.php?g=34307-barph-ahri-build-guide#chap4) that is intended for Ahri. The rune setup they have is below:

The guide lists them too:

> 
> * 9 Greater Seal of Scaling Ability Power
> * 4 Greater Glyph of Scaling Ability Power
> * 5 Greater Glyph of Magic Resist
> * 3 Greater Quintessence of Ability Power
> * 9 Greater Mark of Hybrid Penetration
>

> 

Is this a good rune setup for me to aim for or should I be trying for something different?
