@Riot Any Plans For Karthus?

is known for being good in team fights and his ult. The problem is if you have any mobility then landing phase is difficult for . Take for example. His Q does more damage, has a knock up, and a slow. The AP Ratio is higher so it is better when the enemy is hiding in a minion wave and it has more range and a bigger radius as well. I know the power budget on is he does more damage when he lands Q on a single target and his global ult, but the difficulty of landing Q and the damage is almost not worth it. If the Q was a little bigger or had another component it, then it might make laning phase easier for him. Since most Shadow Isle champions have a stacking or counting mechanic on them, ( resistance with more gouls, three hits on Q, soul gathering, ...) how about adding one to to keep the themen going. My idea was the more single targets he kills with Q he could gain an amount of AP for his ult. And he gains more if it is a Champion
