Pantheon needs to be nerfed

i still feel like pantheon should be nerfed.. i mean like every time there has been a pantheon on the other team my team has brutally lost. i feel like this shield shouldnt be able to block tower shots and he shouldnt have a stun or make the shield duration low or reduce damage instead of completely blocking it, and with his stun it needs to be reduced or completely taken off. And last but no least his passive shouuld not crit at all. i would completely change this passive/ give him a new one.
