JG items prevent champs from getting the first item they really want....
For example, Blue kayn really want duskblade first, but the jg item prevents him from getting it. Same with Diana, she really wants narshors first, but is stuck with this AP item thats not optimal for her.
Am I the only one who gets a little annoyed when I cant buy the item the champ really need first?
on their generic builds, because of the high AD value, 10% CDR, and the on hit damage while the smite is on? Atm that costs 2625. If you took away all its utility, the result would be a cost of maybe 1600g. Any adc would jump right on that.

mainly, because it works so well with their kit.
, but she tends to do better when you start a generic
, because her mana gets sucked so hard, and heals are needed to keep HP up enough
