You barely die from his ult? Do you even play mages, marksmans, and supports? They have 30 magic resistance with no scaling. Karthus doesn't buy Magic pen until mid to late game but once he does that he's hitting you with pretty much true damage and early game it's still 200 to 400 health which is great damage given that it hits everyone everywhere with no real counterplay other than being there to interuppt him and that's where his passive makes him shine.

Karthus is the dead zone. He builds health and mana and takes tons of hits but killing him isn't how you beat Karthus. It's killing him and making sure he doesn't kill you or anyone else. He gets fed by farming his lane and ganking other lanes with just his ult. Late game you have to get him away from your team but not around his team because if he can get a teamfight going in his zone after he's dead his damage can be almost impossible to deal with without running and Karthus has a wall and ult for that.

I don't know how you could get away without knowing this given that even Karthus bot showcases his strengths on occasion.
