Playing a Juggernaut now for me is really sad

I feel like playing someone like right now is rather pointless. With all the lethality builds running around late game I'll have 4k+ health and 150-200 armor and still be killed within 2 seconds by a single champion running lethality. Completely defeats the point of being a juggernaut who's suppose to be immobile and kill anyone who gets into range when I fight a whos Q ani canceling alone does somewhere along the lines of 3k dmg. And don't say those numbers are bullshit I've played lethality Riven and seen it.
