Why does Karthus...

Truthfully..after looking at your previous posts...its all complaining about every champ in the game being OP..so i'm just gonna move alonnnng

Play a single game of karthus You wont be complaining afterwords Karthus is really hard to play due to the delayed time Q ( the spammable ability ) takes to activate mobile champions just escape + hes easy to kill and when I say "easy" I mean a lux can q w R him for an instant kill

Since you say hes killing you in meele range that'd be his E which drains mana like a mofo if you don't like being killed rush and you wont die when he dies get a hexdrinker and then a maw easy counter

Because melee champs don't know how to build and outplay karthus I guess.

Because a good karthus will stay out of your reach and attack with E while slowing you with W and followed by more Q's. To beat him you need burst, and alot of it.

Burst > DPS
