User blog comment:Lykrast/Runes: why I hate them/@comment-5788083-20140326122857

the thing is runes add too much strategy for riot to remove them for example scaling vs flat (scaling are better later but flat can help me snowball) or AD vs Apen (AD better for csing and pen better on champs later on especially)

and runes can change the way you play for example getting hp regen quints as a support makes it easier to start with spell thef's or ruby crystal where as without them you are too susceptible to poke

the only runes you need different types or are marks really you could just get Mpen and AD for most champs
