Items that give mana should also give fury and energy
I was just thinking why the items in this game don't give the stat based on the champion.
Like for instance Frozen Heart should give additional Energy for Energy Based champions like lee sin for instance. this way they would get tons of armor and cdr with the extra energy so that the mana wouldn't go to waste and instead of being a bad item for lee sin it would be a good item for him.
the same goes for energy reneration and fury. Champions like Shyvana and Renekton would benefit from a Frozen Heart that gave fury or fury regeneration. and mana regen items can also benefit champions like kennen who build ap items but are energy based champions who would get energy reneration instead of mana regeneration.
why hasn't this be done is what i really want to know. and don't say "because manaless champions are already OP and this would just make them more OP since they will spam even more with more cdr" because that is not a good excuse.
