1.ezrael, ad sona, ad orianna, ashe (if u play her as w spammer)

2. ad casters usually stack tons of ad, so the slightest bit of attack speed lets their dps sky rocket

(i found out by coincidence, where i got zeke on renekton for the cdr health and lifesteal, my dps rate increased by so far that i could actually be on par with the enemy shyvana, and that with just 1 item )
