Did you actually notice the difference between the actual Sion's base damage and this Sion's base damage?

40 / 80 / 120 / 160 / 200 to 70 / 125 / 180 / 240 / 300

If you would look carefully, you would see, that the max hp ratio actually compensates that.

And if you got like 5000 HP, that is still just 250 bonus damage, where you have to make -100 as the base damage is lower. 150 bonus damage is nowhere near OP.

Finally, do you know that the best adc's always focus their nearest targets and go as far away from them as possible? They do not care if they hit a tank or an enemy carry. They kite their nearest target.
