Riot it’s not particularly fun or fair to be murdered in spawn by a Karthus that just runs into spawn while we are all dead, kills himself and lets his passive continually murder us again with no counter play since we don’t heal at spawn.
My suggestion would be to disable Karthus and other similiar invulnerable death passives (such as kogmaw) when entering the opposing team’s spawn point in ARAM.
I feel like if karthus actually reaching your spawn, and you're collectively stuck on the spawn anyway instead of just running off, the game is pretty much over regardless.
Karthus has no other passive aside from his death passive. If Karthus somehow never dies for an entire game, he is denied a passive to use, compared to other champions who have a passive all game long.
No one likes to have an unkillable ghost firing spooky ghost skittles for 7 whole seconds, but it is what it is. Karthus has one of the most expensive passives to use, meaning he has to die before he can use it. That 7 second of ghost-time means he has 60 seconds of grey death screen as a cool down.
