Karthus fun or not?
Title. 
Title. 
at least every 3 minutes
he's a fun and silly champ, but i still miss furor+rylais for the uncatchable ghost. The new masteries have done some good work for him though.
i remember in one of my games, every single time I press the R button, soraka press R right away to ruin my fun.... every single R.
I love playing as Karth. You exert global power even when you're mid because of your ult, and you can snipe people who JUST manage to get away from being killed. His passive and E make it so even if you die you aren't useless, and your team can and should position teamfights on top of your corpse.
I also like how his Q is basically built to be his CS tool instead of last-hitting.
I feel like people either love him or hate him lol. Some people dont like his Q cuz its a spam ability but it also has a delay so mobility might get the better of him depending on the matchup but if you don't mind how his Q works then he is actually really fun to play IMO :)
Super fun
I like to play him once in a while But I find it funny when u ult and u seeing the enemy team accepting their death when their low
