i just noticed the new olaf is the old sion

old sion had 100% lifesteal ulti. But olaf also have 100+% lifesteal.

olaf with botrk bloodthirster and zeke have 40% lifesteal.

his W add 21% more.

so its 61% lifesteal total.

add the 10%lifesteal potion so he has 71% total.

buy a spirit visage so he get 1.2X multiplier so he get 85% total.

olaf at low health gain 50% multiplicative healing bonus. so he get 127% total lifesteal.

and then you add the second wind from defensive mastery : +10% extra healing multiplicative : total : 140% lifesteal

you can be sure it's not easy to counter 140% lifesteal. olaf es op and need immediate nerf.
