We cast Kaido wrong all the time.
In fact, he can beat all 3 admirals.
Kaido unnerfed, without an island on his back made 1v9 in basic form.
Nerfed Kaido had to use the hybrid on the SNS and retired it on LAW when he got a little serious in a BLITZ.
KAIDO base without nerf islands, it makes an average difference to us 5 SNS.
