@Riot can we get a buff to JG Karthus?
Lately, I've been really trying to get JG Karthus to work, (with a bit of inspiration from NightBlue3) but I've noticed that when Karthus is in the jungle, his damage isn't as consistent as when he's laning. Which got me thinking that maybe if his jungle playstyle got a bit of power. It might compensate for his lack of damage.
I think that the one thing that should happen is to have his E deal %50 more damage to monsters (which excludes lane minions).
Now this may sound a bit odd as a way to increase his JG power, but Karthus is considered a Hypercarry in that his damage is improved mostly by his item kit. This basically means that the more effective his clears are, the faster they are, and the faster they are, that means that either he can gank faster, or go clear more camps. Either way, Karthus gets a little more gold in his pocket to spend on essential items to get to his mid-late powerspike.
