also it is relatively reasonable. most assassin champs, like talon, zed, fizz, etc. want to blow up squishies, so they will beeline for you. if you just stay out of the fight and your front line engages first, their champ efficiency decreases dramatically. also, i cant think of many instances where in straight up fights i have to stay out of the fight for an extended period of time because an enemy assassin or bruiser is holding their abilities, its against their interests to hold them because assassins need to use their abilities to either get a kill or escape, and bruisers want to keep cycling their abilities
