Wait, no more CDR runes??????
Those changes will completely ruin my gameplay with some champions. I always found that scaling CDR runes offer the most value on some champions. In fact, on Zac i run 30% CDR runes, with a spirit visage, i reach 40% which allows me to spam my abilities lategame. There are no other decent CDR items for Zac, Spirit gives only 10%, Frozen Heart and IBG both give 20% but mana is wasted on him so their cost efficiency on Zac is way off.
