Talking about Karthus, since we gave Graves his cigar back... (and jungle Karthus talk)
Can we please give our favourite preacher of death his face back since we can ship now the bone-free version to china? He's done stacking 6 tears but he says nothing will fill the void or ease his pain...
On a less cosmetic note, I really fucking love Karthus, his theme, his eerie aestheric, his playstyle, having 5 people yelling at me in /all chat whenever i press R and have my team curse at me for securing kills as well... I love it all. Especially because (surprise surprise) HE'S A PRETTY DAMN GOOD JUNGLER. (As his champion spotlight says as well but in case there are some miscreants here's an example of his clear, which still has room for improvement) https://www.youtube.com/watch?v=IzJuIwwN95k For those who don't know Karthus has seen jungle play since the earliest seasons thanks to an unknown to most guy called Azingy and he has a pretty good success since once you learn how to kite you can have pretty fast and healthy clears, some decent ganks and you outscale into late game as well, but he has been hit pretty hard since the Ryilai nerfs that make sense for champions such as elise who can still build that item but doesn't fit well in a build suited for a pure damage carry such as karthus, he also needs to stack tear as well but some would argue that's not a mandatory item on him after all. He suffered from the Zhonya nerfs as well since right now is built by champions that have their strenghts in their kits and just need the zhonya for the cooldown and active, which they were both core items on him. His ult cooldown may be fine for season 3 standards but right now is really damn long especially because none of your other spells need their cooldown reduced so building it on him just to reduce the cd on a spell that has a tactical use only insead of being "some more damage" and thus in need of cooldown reduction is pretty much wasted stats on him.
What could be done with Karthus is
- Buff his wall (which was heavily nerfed due to Rylai but wasn't unnerfed back after the Rylai nerfs) so that he can have a realiable tool for CCing during a gank. (Also a trimming on this cooldown wouldn't hurt either)
- Maybe make his Q apply red buff? So it doesn't feel as a wasted buff on him unless he's taking down a turret or regenerating his HP.
- Increase the tick rate of how often E gets applied (this doesn't increase the damage for those who are wondering) so that you don't waste a tick on a jungle monster that would have died anyway even without the need of E damage.
- Bring his ult cooldown to current season standards.
- Find a way around his dependance on Zhonya since right now is a pretty bad item unless you're already good with your own kit or other items that compensate
The build i believe to be correct on him should be a classic build with jungle item, lotsa of magic penetration and high end AP items suited for a classic AOE mage with no CDR, something like this

So, this boils down to: can we make some work on him to give him back viability for mid lane (which doesn't seem to suffer much there) and jungle as well?
