Zac 46.8% winrate, Sej 51.5% winrate.

Sej is powered by angry bacon, thus she is awesome.

zacs engage is pretty telegraphed, he offers less hard cc, his survivabillity in clashes is rather low as it'S hard to gather his passive-blobs, his engage can rather easily be prevented by cc.

Seju can use Q+R to get 1.75sec aoe stun followed by a massive slow from a pretty huge range, u can didge the ult, but it'S hard, and u can'T realy prevent it with cc.

so while both can go tanky and still deal good aoe damage while oggering great aoe cc, it's just way easier for sejuani to actually apply the cc

One is a girl and the other a boy

One is from Japan, the other is not.

Sej also has arguably one of the best ult engages in the game.

Zac's damage was hurt several times, because he isn't allowed to solo a adc

Zac has been nerfed to oblivion.

They need to buff him again, meeting halfway with his current nerfs compared to his release state and add back tenacity (at least 50%) to his ult again.

Also his W change was more of an overall nerf, increased CD by 1 second. No matter how many blobs you keep picking up to reduce the CD, it's a nerf flatout, for those 2 useless extra W's during fights, if you miraculously happen to land on the blobs of your ult before being molten down by 2 auto attack from any ADC while being a full tank.

Zac is overnerfed.

Granted he was complete cancer when he was viable.
