Riot Logic

Let's make a tank champ... that's ranged... has no mana... has infinite life steal... superior wave clear... an ability that damages, slows you, but makes him untargetable... an ult that amplifies all damage you tank... he rushes and gets full life steal everytime... followed by to make him untargetable again and increases his lifesteal by 20%... then cause now he has 3000k health and can sit under turret like and regen his full health in like 20 seconds.

If you guessed ... you're correct.

We make a champ like this but and take out the only item in the game built to counter this (executioner's calling). So I'm basically forced to cast my before I engage him, just to have a chance.
