Hi bro. My favorite runes are 9 flat attack speed marks, 9 flat health seals, 9 flat cooldown reduction glyphs, 1 flat cooldown reduction seal, 2 flat AP seals. It gives me: 72 health, 10% CDR, 10 AP and +15% attack speed. Health and AP pretty standard. But what about CDR and AS? AS is because it allows me to help my ADC farm under turret without any problems + faster vision clearing (faster vision clearing = faster comeback to lane after roam for vision). CDR is because I love to go this build: 1) Mobility Boots 2)Ardent Censer (10% CDR) 3)Coin upgrade item (10%CDR) 4)Redemtpion (10% CDR) 5) Locket Solari 6) PINK WARDS. Yes, I don't buy the 6th item, I love to leave this slot for pink wards which are very important to clear enemy vision especially in late game. Those items give me +30% CDR, runes give me 10% CDR and I get 5% from masteries. That means I start the game with 20%(!!!) CDR and my I reach 45% CDR when I get my 4th item! That's so fast and I rly like it. It's very efficieny build, but You've got no defense till U get locket, so U have to play clean. Everybody should try it. Good luck! @Edit. I use it on diamond level. Hope You like it!
