swappin out my CDR runes. would like advice pls
so my 2 go to midlaners for when i need magic dmg are 
and 
and on both of their rune pages i would run 15% scaling CDR glyphs to get near the CDR cap with 1 or 2 items, but with CDR being introduced to Zhonyas and abyssal scepter i don't wanna overcap super hard, so im looking to swap out my CDR for something else
either AP, AP scaling, or Magic pen glyphs on to maximize my damage (don't know what would be better tho)
and either mana, scaling mana, mana regen, or scaling mana regen for (to make up for the loss of mana regen for mages)
what do you guys think i should do? or do you have a better idea?
