I personally like the AS (attack speed) quints to AD quints. Here's the reason behind my decision: With AD quints, your overall attack damage increases, which helps you deal more damage in trades and land last hits. However, your passive kledw.png has a 150% increased AS bonus and is overall your main damage dealer. Without any AS items, this takes about 3-4 seconds to proc. Because this is Kled's main source of damage, you'll want to proc the 4th hit asap, which is why taking AS quints is better than AD quints.
